Okay, if we're making a list of things we've learned:
1) Fuck this stock shit. I'm with Ryne -- it sucks to have everyone (EVERYONE) blow by you like you're standing still. Riding with the pack is what makes this kind of stuff so fun, and stock peds simply can't keep up. Not being able to keep up = not as much fun.
2) On a road trip, you should always go to the bathroom when you're stopped at a gas station because you never know when you'll have another chance to go. On a moped ride, you should always fill up with gas when you're stopped at a gas station because you never know when you'll have another chance to fill up.
3) Like shit, lost happens. (A lot.)
4) Sunscreen is your friend.
5) People who ride mopeds are awesome. That's not exactly news, but it was really cool to know that everyone was watching each other's backs. There was always someone willing to lend a hand or a tool, and it was a beautiful thing.
6) Follow the leader is easier said than done.
7) The only advantage of being slow is that you can more fully appreciate the looks on people's faces. I saw a guy on a Harley turn his head as I drove by (after he'd already seen the other 199 out of 200 mopeds drive by) and kind of shake his head. I saw a woman standing at her window watching the moped view. I saw people coming out of their houses to take pictures of the scene. I saw people on the street stop and stare in awe (or perhaps disgust). I'm sure some of you fast people saw some of that too, but I'm willing to bet it's easier to see people's reactions at 25mph than at 40mph.
