If you need a ride to or from your trailhead or river trip put-in point, a couple of Moab companies provide the service (and also provide airport shuttle service by reservation), with vehicles large enough to handle groups. Coyote's website is worth checking out for trail and river conditions and other information. Enquiries for Roadrunner are handled by Dual Sport, under the same ownership.
