I would say the 45th intersection is a complete wreck compared to what it used to be.
But overall, things have gotten very ritzy on the south side of the Ave with very expensive new residence halls, 5 times better than Hagget, McMahon, and whatever those ones by Eastlake bridge were.
I actually think it was shittier in the early '90s when it was a destination hangout spot for high schoolers looking for exoticism.
There used to be a place that sold bongs and dildos and band posters when all of those were considered risque.
Tower records, cellophane square, also the old cellophane square. Magus books.
If you were a cool or smart person, like me, the ave was great. Also, believe it or not there were always hot sophisticated chicks hanging out certain locales.
