As I get older I find myself saying things like "When I was a kid, this used to be a post office." and boring anyone who is polite enough to listen about what used to be what. The town I grew up in has grown quite a bit and honestly, most of the changes were in the last 15 years so it's not quite like I'm a grandpa on the porch swing cogitatin' on days gone by.
I was just reading an Archie's comic digest I picked up at the store the other day to see how the gang was doing. It seems that Riverdale now has a supermall complete with an indoor amusement park. When I was a kid there was just a malt shop and a few stores.
Now I know I'm old when I can point out that the fictional places of my life have undergone urban sprawl.
