"Pace won't be mach retard but will be brisk. Wear gear, and ride your own ride, we wait when route changes."
^^^^^this last sentence is what I like most about the O.R. Rides I've been on. When the last rider makes it to the intersection there are smiling faces waiting. "Ride your own ride" seems to hold true. Some of these guys are damn fast and when they need to scratch that itch I'll see them at the next stop sign. Hell I hope someday I can handle a bike that well. I think the way @theroamr posted this up is a good thing. Tells me that if you drop off it's no big deal they'll happily hold up at the next stop. That's a pretty welcoming attitude.
I think the only way we figure out who we're comfortable riding with on here are open invitations like that one.
