Have you heard of Urban Golf? It sounds like a fun concept for those who can't make it to the golf course or are tired of that scene or can't afford it. You can play it just about anywhere but do be considerate of others. You can see a website with rules here (via BuzzFeed). There's also an Urban Golf Association.
Philadelphia Weeklyreports that the game is really catching on London, Seattle and San Francisco. They talk about people playing urban golf with an Almost Golf ball or a "leather orb."
Urban golf is just like its grass-cut cousin, but designed for fans of the gentlemen's game with no access to snooty clubs or expensive gear. Urban golfers just grab a thrift-store 5-iron, beers and some desolate cityscapes (Philly has a surplus of all three), and presto-the entire city is your fairway. No fees, no dress codes, no bans on Jews or blacks or Mexicans or women, no dressing like a total dick-just good, clean dirty urban fun. Anything can serve as a hole: trash cans, lamp posts, even storm drains (for that satisfying "sunk putt" feeling). Some golfers use a plastic Almost Golf ball that travels about a third the distance of a regular ball and won't break windows. Others prefer a leather orb filled with goose feathers, which won't roll into street gutters and just sits up to be hit. Now a common sight in London, Seattle and San Francisco, urban golf has yet to catch on in Philadelphia despite our 900 acres of vacant, blighted land.
In this video below golfers play an organized game of urban golf at USC. They write, "We actually were able to play through the USC campus without killing anyone. This ball was amazing. It is super light, but has CO2 pressure inside so it goes a nice 50 yards with a 9 iron, you can work it just like a golf ball, but it won't break windows or dent cars or kill anyone. That rules."
