Something to do on a rainy, drive to Frederick.
Our first experience at Sonic. Stayed in the car, food delivered on roller skates, boys had Slushies filled with nerds (yikes, I had to give in since this was to be a special trip) and I had a milkshake, yes we did get other food but not as exciting as the drinks.
Planetarium. Watched a Bug movie in the Planetarium and then taught about the stars in our sky and how to find them.
