FORUM: Three-Over-Two
Concluding my morning walk along the fishing docks, I took the stairs to the second floor of the Point Loma Sportfishing building. I wanted to wish Lori, who runs the American Angler business office, a great morning and a wonderful day. The “Double A,” as anglers affectionately call the boat, is one of the celebrated … Continue reading FORUM: Three-Over-Two

Athletic activity has served me well as a favored pastime throughout my life. For me, athletics is an enjoyable method of reversing physical withering resulting from long periods of primarily motionless sitting when working at a desk. Athletics provides an applied setting in which to employ scientific and engineering knowledge and evaluate specific measurable personal … Continue reading FORUM: Sports
FORUM: Falling
Seven months ago, an endodontic dentist performed a root canal upon me to “cure” a parulis condition. When I arrived for the procedure an office worker called my insurance company and learned that only $200 of the $1,000 total cost of the procedure was covered. I paid the $800 difference and was told that the … Continue reading FORUM: Falling
FORUM: Macho Fireworks
Presently I live in Chicago in a fifth-floor apartment facing Lake Michigan—about half a block away. On the 4th of July—ten days ago, after darkness set in a bit past nine o’clock, a hoard of inebriated amateur pyromaniacs began flaunting their arsenals of consumer-class fireworks. As usual, their displays demonstrated a dearth of individuality: impotent … Continue reading FORUM: Macho Fireworks
FORUM: My Big Yellowtail
I was one of 24 anglers aboard the American Angler on a 10-day long-range fishing trip to Alijos (“Ah-lay-Os”) Rocks, a group of tiny, steep, barren volcanic islands in the Pacific Ocean located 190 miles west of the Mexican mainland, and 550 miles south of San Diego. Charted on Spanish maps since 1598, Alijos Rocks … Continue reading FORUM: My Big Yellowtail
FORUM: Fishing Seal Beach Jetty
In my lifetime thus far, my favorite place to "shore" fish was the Seal Beach Jetty in the early 1970’s. Emptying into the Pacific, the San Gabriel River ran beneath and perpendicular to Marina Drive. The southern side of the jetty was composed of large rocks, which extended westward into foreboding deeper water. I fished … Continue reading FORUM: Fishing Seal Beach Jetty
FORUM: Birds of Prey
Thus far, I’ve lived in eastern seaboard, southern border, west coast, and Midwestern states in the US. I’ve explored prairies, woods, forests, deserts, wetlands, rivers, and beaches everywhere that I’ve lived. In this activity a few vertebrates I’ve encountered in the wild triggered my consternation. One species was venomous snakes, particularly Sidewinders in Arizona (https://odajournal.com/2021/01/27/forum-sonoran-desert/) … Continue reading FORUM: Birds of Prey

I took my first-ever college courses at George Washington University (GWU) in the summer session after my seventh year in elementary school. During this time my family was moving to California, but they stayed with Mom’s family in Chicago most of the summer.

FORUM: Dogs and Cats
My parent’s family, and my family, supported numerous types of domestic and working animals over the course of our lives. Some creatures were hardly memorable because they had limited personality or intelligence, lacked affinity for family members, or lived a short time. However, some of our animal companions were unforgettable because of their uniqueness. Useless … Continue reading FORUM: Dogs and Cats
FORUM: Siberia
I owe my existence to the onset of World War II. When Germany attacked Poland from the west, Russia attacked Poland from the east to keep the German army away from the Russian border. My grandfather was an estate owner and Cavalry officer, so he and his family were sent by train in cattle cars … Continue reading FORUM: Siberia
FORUM: Casting Overhand
Emigrating from Virginia, I was an eighth-grade student in Huntington Beach (HB), California—home of the US Open of Surfing. Whenever the opportunity arose I fished for Bonito at HB pier in the morning bite. When I arrived at the pier I saw surfers most mornings—wearing wetsuits, sitting on their boards in water not far from … Continue reading FORUM: Casting Overhand

As an aide in developing ideas for Blog Posts I examined photos taken across my life (thus far) to help me recall my past.

Ross and I were going tile fishing in Atlantic canyons off New York. It was my first time. Reaching these fish requires sending bait 800 to 1,000 feet deep using between two and five pounds of lead weight, depending on the current. We arrived at the canyon and I made my first drop using three … Continue reading FORUM: Electric Wahoo
FORUM: My Big Wahoo
The first pelagic fish which I ever caught was a 49-pound wahoo—one pound shy of a trophy for this species. I caught it by casting a sardine pinned in the nose using a circle hook tied directly to a fluorocarbon (monofilament) leader. The fish was landed in a few seconds after ramming the side of … Continue reading FORUM: My Big Wahoo
