So 5 billion years ago when we were staying in Ohio, we went to the airforce museum in Dayton. This place is crazy-awesome. Number one - it was free (maybe not now with all the shutdown in the US?). Number two - it was huge! There were 3 huge big buildings full of planes and airforce memorabilia and then heaps of huge planes outside too.
We spoke with people who had been to the airforce museum in Washington and said this place is way better! So, you know, if you happen to be hanging out in Dayton, Ohio, Hit up this museum!
(P.s. it took us two days to go through the whole thing!)
