Me and my buddies are planning a trip from Seattle down to Vegas then over to the Grand Canyon and home again. Can it be done in 5-6 days? And if so what is the best route? and is there anything else, (baring the time constraint) that we should see. We have 3-4 guys who can take turns driving so we should be able to log some long hours on the road if need be. Any comments or advice would be helpful. Thanks.
