Not sure the exact rules ( i probably should look these up), but no bars or places open to the public (parks and shit). And alot of buildings have a certain distance that you have to stand away from them.
i'm coming to new york on friday and want to try to get in a game at Rucker Park. what's the best way to get there from midtown
Take the B train from Columbus Circle to 155th, should be like a block away. Good luck though, it aint gonna get over 45 degrees this week.
