The other day I drove through the neighborhood where I grew up and looked at my old house and the houses of the friends I grew up with. Everything had changed.
I ate my lunch (from the local McDonalds, which has been renovated a dozen times or more since I moved) in the parking lot of my old elementary school. They took out the basketball courts where I learned to play tag and wiffleball and replaced them with new "safe" playground equipment. The only part of the old playground equipment left is a lone swingset, which must be 50 years old this year.
