If you've ridden on the Va. Creeper (we're going next Sat!), would you choose to ride:

Mountain bike with knobby tires

~or~

Bike Friday Pocket Crusoe (road bike) with 1.3" slick tires

??? Obviously the Bike Friday is lighter, and the tires are wider than a typical road bike, but if the knobbies would be more appropriate for the trail, I'll take that one.

Thanks!
