Any mt bikers in or near Scottsdale, AZ?
 

I'll be going to Scottsdale next week for a convention, and I plan on renting a bike and skipping a good portion of the meetings. :D What I'm looking for is some fast, twisty singletrack I can spend at least a few hours on.

The convention is at the Fairmont Scottsdale Princess resort, and I may be renting a bike from AOA Adventure Tours, which is located near McDowell Mountain Regional Park. Are the trails there worth hitting?
