I saw them almost to Ritzville on the 22nd, about 0800 hrs. This is an odd route to take to get to the Loop. Go east on 90 to 15 and head south through Salt Lake to 70 ? Snoqualmie, 4th of July, Lookout, Monida Passes, .... Seems to me a lot less mountain passes would be encountered going south from Seattle to Portland and taking 84 to intercept 15 near Pocatello and then down through SLC to 70. Jerry, .. is the Loop destination just a guess ?
