The boat ramp thing is true. I fish alot now that I don't ride, and it never ceases to amaze me the stupidity and inconsideration of fellow humans (I use that term lightly).
I enjoyed Sprocket, RBC, etc. mainly because he got such a rise from y'all and his arguments were at least clever. This Dead guy has no logical argument.
I don't post much there, either, mainly because of the hysteria towards LA. I think he doped as much as anybody, but I have a life in spite of that. And, I am unwilling to suspend protocol to catch the guy. All the threads devolve into the same thing, as you note.
For a new hobby you should try trolling various newspaper bulletin boards or fishing/hunting boards and write outlandish and inflammatory posts to get a rise out of the locals. I just found a new one that is very promising, after messing with the Oprah Winfrey one for awhile. I wasn't getting enough attention in there. If you think the clinic is bad, those Oprah posters are totally out of whack.
