If I can't hit it right at 5-5:30Ain't that the truth! My personal favorite time is Saturday mid-morning. It's always fun to spot the folks who have just started cycling; you know, $4,000 bike with $1,000 of accessories. And, of course, a yellow US Postal Team jersey. Still, at least they're out there trying to get fit...
Saturday evenings are pretty sweet. The spots where the entrance areas are few and far between are good too.
We have a 13 mile straight line trail about 20 miles from my house. There's points on that baby where I can go miles without even seeing someone.
I try to be nice to people who are new and don't know any better. I can be a real ass to people who should know better ;)
