US 50 is a beautiful route. I-70/I-25 will be much longer & has quite a long, hard climb from Vail to Georgetown. On 50, is the very nice small city of Montrose. A good place to stock up. Gas is cheapest at City Market. 50 takes you pass Black Canyon of Gunnison Nat'l Pk. A MUST see! Their campground up Rt.347 has electric/water on one loop. Sites large enough for U. The drive up 347 is quite steep in one place. At the junction of 50 & 347 is a very famous antique/nicknac shop. Everyone stops in to browse & is a good place to unhitch the TOAD so its easier to go up 347. Monarch pass is the only real climb on the route, altho not too bad, I always unhitch the Toad for the DW to drive. Pass Salida u travel along the very pretty, but curvy Arkansas river. Its a bit slo thru this section but beautiful drive. U'll go pass the Royal Gorge attraction near Canon City. If it open, big fire last year, its an amazing site to see.:)
