Ended up hiking the Riverbreaks trails Sunday AM. Did a 4.5 - 5 mile loop on the East Section of the area. It was great. There were some trails that would be really fun on a down hill bike. Looonnng down hills, wide open, I bet you could carry 35 mph without too much effort.
Afterward, met Rusty, Ray, and Randy (R^3) at Sunbridge. Things were a little wet, but not slippery or sticky. Rusty climbed the big hill that almost everyone walks. On a single speed, I don't think climbing it is even an option - but Rusty ripped up it on the gears. I even saw him stand up out of the saddle, almost didn't recognize him at first. Congratulations man, what a climb.
We also went looking for new trails at Sunbridge. Found some really overgrown stuff that required lots of hike-a-bike. Then we ended up climbing up the side of an old motor cycle climb, which was nearly straight up - tough with a bike slung over the shoulder. Definitely a challenge, but it was something different that kept things interesting.
