Adams MorganRandom Is The Gym At The Bottom of 18th Street in AM Closing? by Prince Of Petworth March 5, 2009 at 12:15 am 15 Comments DSCN6893, originally uploaded by Prince of Petworth. Just noticed a big sign outside the boxing gym located on 18th Street just north of Florida. Makes me wonder about these tough economic times. Are people canceling their gym memberships as a cost cutting measure?
