The past is all around us. There's a state park[1] I run in many weekends. It has seperate north and south entrances that are about a 15 minute drive apart, with no road between them within the park. I was curious why the park was built this way. It turns out the park was literally segregated till the early sixties and the north side of the park was for the white folks and the south side of the park for black folks.
