So far, we've spent about $125.00 on gas, $340 on hotels (more than budgeted, but heck, I didn't know about the motorcycle rally!), and less than $100 on food, due to bringing a cooler and eating leftovers.
Best so far: the scenery of Montana
Worst so far: high prices due to motorcycle rally
Kids favourite: the pool at our last hotel
DH's favourite: Devil's Tower
My favourite: Mt. Rushmore at night
