For Spring break I took my kids to the Tree House Museum in Ogden. May I say it is one of the best little museums to have your children lose themselves in. Ogden kind of has a bad wrap, but this little downtown area is sure spruced up and fun to walk around. I have a few crappy Iphone pictures-- but I would say to give this place a try.
PS When I'm in these museums I secretly wish my soon to be basement was organized into all these little themes (castle, blocks, hospital, house, barn). What a wonderland that would be for my kids! I would just need to hire the workers to follow behind them to keep the toys all nice and compartmentalized.
