3 of us will be in Moab w/ the rest of the mtb. community in April! Wondering how important a car is? We may fly into Moab. Car rental there is pricey. How far is it to the trails? I know they have shuttles to Porc. Rim but what else? We're wanting to do Sovereign, Amasa, Porc., probably Slick Rock and one other. If there is a lot of road riding we will want to rent and we'll probably fly into G.J. since car rentals are half the cost of Moab. Thanks for the help.
