It's amazxing what one remembers 40 years later. My memory says on the resturant end of Plum there was a sad little city park/playground, and I remember thinking that if the developer wanted to do something nice for the community they'd clean it up and reseed it with grass.

I think I've told this story before, but when I was at Northwood, I'd hop a bus down Friday after class, spend Friday night at the Chessmate then get a cheap room at the Hotel Grandwood, and spend Saturday night on Plum Street before catching a bus back to school on Sunday

The Wisdom Tooth was an all ages folk coffeehouse that did after hours jazz.. Probably the only place on Plum that had any real legittimate tie to whatever arts community there was in that area. Most everything else down there were the types of shops that migrated to The Trading Post.
