We will be travelling from Michigan (leaving May 6) to Arizona (arriving May 10. We would like to travel thru Colorado and are not sure which route to take to see the most in the shortest period of time. We were thinking of possibly seeing the sights around Co. Springs and then travelling HWY 50 to Montrose,then HWY 550 south. But we weren't sure how long that would take and if we might encounter snow up in the mountains that would delay our travel. We have to be in Phoenix on the 10th. Any suggestions??? Thanks a lot.
