Head out to Bushwick, where a mere $5 will get you a ball, club and the chance to play on 9 putting holes designed by 9 different artists in a formerly empty lot deep in East Brooklyn. Mostly designed from reclaimed materials, the different installations range from a pink soda bottle forest and lake to a storefront bodega where you have to shoot your ball through an old stand-up video game. The first hole is a clever simple stretch of "green" that is simply a photo poster of the garbage that was in the exact spot where the green sits.
It's easy enough to get to. Just take the L-Train out to the Jefferson stop, get out at the Jefferson/Wycoff exit and walk a block to 12 Wycoff. Done. Afterwards, grab some cheap tacos from the highly rated Tortilleria Mexicana Los Hermanos, a few blocks away at 271 Starr Street (between Wyckoff Ave & St Nicholas Ave). There's a map on the link.
