We took the kids to the Minnesota Children's Museum and were there for 3.5 hours. Isabel had a ton of fun and didn't want to leave. We got to all but one of the rooms. We still have not been able to do then entire museum in one trip, but this time we got in the room we had not been to before (the craft room). Once it gets warmer the rooftop garden will open and we will have one more to try to get in.
