Our camping was granted a short hiatus as we stayed in a hotel in Boise midway through our trip. This was to ensure we could get laundry done. (Incidently - the facilities vary at parks, and at Yellowstone, they are so good I think we could have done all this there). It was also good to give the kids a break, get them into a real pool a couple of nights, and take some indoor time. Boise has a good kids museum - sort of the "Exploratorium lite." We were lucky - they had a bubbles exhibit, which Sean just loved! They had places to make shaped bubbles, bubble tubes, a bubble wall, and Sean's favorite - Giant bubbles!
It was right next to some of Boise's city parks as well, so I was able to bring a lunch for the boys. I think a lot of people picnic there - the squirrels were not shy about trying to demand food. Sean Enjoyed feeding the ducks.
