Me and my boyfriend are from Detroit and are currently planning a road trip outwest. We would like to see Mount Rushmore, Yellowstone, Yosemetee, Hoover Dam, Texas, Colorado, Vegas,The Grand Canyon and end up in California. We have about 23 days to do all of this. As far as the dates go we were thinking December 15-Jan 6th. Now I know this will be in the winter and I'm slightly nervous about the road conditions just because we will be in the Mountains!! Any feedback would be awesome. I would like to start planning as soon as possible:) Thank You in advance!
