What exactly does a "tour" consist of? I read somewhere (Dog Fancy?) that dogs are allowed on a certain rim of the Grand Canyon, but I can't remember which one. I haven't been there in years I don't even know how many "rims" there are. *Edit just read some info from www.thecanyon.com they are allowed on all rim trails, just not below the rim trails, and the south rim is more recommended for people with dogs.
