Listening to Reefcast on my MP3 player is officially responsible for the "Weirdest Look I've Ever Received" award...
I ride a large motorcycle (Honda Valkyrie) and have a MP3 player w/ amplified speakers clipped to the handlebars...
I was at a stoplight, listening to Reefcast. Good-Ole-Boy pickup pulled up next to me, window started to come down, this happens quite often. I usually get a "Nice Bike!" type comment, and that's it...
The window came down, the guy listened for about 10 seconds (I don't even recall what they were talking about, much less which episode it was), and suddenly the window was brought back up really really quick, the driver wouldn't look at me, eyes straight ahead trying to not acknowledge my existence...
Considering I usually listen to stuff like acapelle pirate music or bagpipe music while riding, the fact that Reefcast out-weirded even those is definitely saying something!
