interbike is in town. I found this map amusing -- check out the trail names!

RMLT passes Bootleg canyon past Railroad pass before Boulder City if riding counter-clockwise, and approaching Railroad pass ascending from Boulder City if riding clockwise. Be advised that the road/touring bike won't make the Darwin in these canyons.

So, I rode my ancient 27 inch Fuji to Bootleg Canyon and caught some sights.
