I'm going to try and make it as interesting as I can and cover as much ground as possible.
"Interesting" as in, let's run all the trails?

No stopping to chit chat, check out the scenery or watch the entire group run over the same obstacle we've seen a thousand times?
I'f I'm on your rear bumper, ignorantly honking my horn, move over and let me by!
If you get a flat, get off the trail. Don't need 26 people held up to fix that.
If I can't see you in my rear view, you're too slow, step on it!

Or, "interesting" as in, lunch at the falls?
