I'm in Gallup, New Mexico right now for the night. Will be driving into Phoenix tomorrow ... But I think we're going to take i10 back to Dallas next week. How much time will it take to get into the Grand Canyon? I assume it's off i10 from flagstaff? I'll figure it out just looking for some suggestions. - - - Updated - - - I think that we'll go straight to Phoenix via flagstaff and we will do Grand Canyon trip on the way back home. Just sends like to long to go from Gallup to Grand Canyon ... slabs a couple of hours there and then drive to Surprise, AZ.
