On our way out of Washington DC, we stopped by the Capital Building for my Dad. He was excited to peek inside & see what we could see.
They offered lots of free tours & other things, but we just didn't have any time for it. Trek & I will take the kids back sometime in the future & do a full on tour for them, but we had to head back & get the rental car back to the airport. We also planned to visit Mt. Vernon on our way home, so we only got to enjoy the Capital from the outskirts this time around.
