We aren't talking about sitting on the bank and fishing in the pond here. Off shore fishing IS an extreme sport.
Oh, I know; I've fished saltwater since I was old enough to cock the bail on my granddad's spinning reel. Every other year or so, a bunch of us would put together a fishing charter, but going after billfish is very expensive to do that way. Better to visit the rigs and load up on Amberjack and Cobia. Between the rigs, we'd usually toll for Pompano. Not high-end gamefish, but plenty of fun ('specially those big Cobia).
It'll be a few years before I get to do that again; all of the charter boats that I used to book were taken out by Katrina - either washed a mile inland or just plain gone without a trace.
Ironically, I've heard that the fishing has been very good in the Gulf (dammnit).
