Oh, he's no myth. He's real. I've seen his posts as RobSwift on Starboard's "Kevin's Corner" forum.
And he has posted on my blog as Robert Bruce, which is his real name.
I can't tell if he is deliberately trolling for negative responses with his often silly and annoying posts, or if he is truly doing his best to participate positively in the outdoor sports community but simply lacks the social and athletic skills to do it.
