OK, here's a humorous subject--farting! I've found that Power Bars make me do that, and I'm wondering what's in them that causes that. Anybody have any ideas? If it's something commonly found in all energy-type bars, I may be screwed for finding adequate on-ride fueling. After all, I don't want to offend those behind me. So I'm wondering if this is a common phenomenon, or am I just weird in that?
