How about this leisurely game which is kind of popular here in N. Ireland.
You need to have 18 bars close together. Belfast or Dublin are pretty good spots for this. I'm sure you people in the USA have plenty of suitable towns.
Each bar is a hole. At each hole you drink a pint of beer (Guinness usually here). The number of drinks you take to finish the pint is your score for that hole. Score keeping might get a bit tricky after a while.
A fun variation is as follows: The pint you drink gets you "on the green" and you then have a shot/slammer that represents the putting.
