The first day in Frankfurt was spent getting the car, dropping off our luggage, and going out to dinner with my parents. The next day my parents had to work so we explored Hessenpark on our own. It's a replication of the last 400 years in that region. It was a great introduction to everything we were about to see over the next two weeks.
The boys got to do some woodworking and left with a top and a mushroom.
