Keystone Mini-Golf & Arcade shared by @onthegrid says: ""Keystone Mini Golf & Arcade, South Kensington by Melissa McFeeters. I won’t lie: at first I turned my nose up at the idea of indoor mini-golf course at Keystone, but after finally visiting I have changed my tune. The holes may not be good enough for Myrtle Beach, but they’re fun and uniquely Philadelphia. In addition to the 9 indoor holes, they’ve added 9 more in the courtyard, which I can’t wait to hang out in myself. And don’t forget that you can bring your own beer (you have to play a round, of course) for extra fun."" on Postcard
