How short is Long Alley?
It's half a block long!
It starts (or ends) at College Street and ends (or starts) at McClure Alley.
Still don't have a clue where Long Alley is? You know where the SDES Hall, aka Portuguese Hall, is on 7th Street. Long Alley runs behind it.
The Husband and I wouldn't have known about this possibly shortest alley in town, if it weren't for taking a walk.
