Hello! Yes we are also traveling in July 2010!
Here's what I have so far: 7/7 arrive at SLC airport and drive to Signal Mountin Lodge in GTNP for 2 nights. Then head to YNP for 2 nights (maybe stay at Grant Village or Canyon). The bulk of our trip will be at CM Ranch (7/11-7/18) near Dubois, WY. I know we will be backtracking with Signal Mnt to YNP then to CM Ranch. I could not get Signal Mnt for my second leg of trip. So what are your must do and see with my plans? Thank you in advance!
