Tennis for me(and ultimate frisbee, although not so much in the past few years)! Tennis is one of the few things I have found where I am completely comfortable going up to a stranger(maybe they are on a court, or have a racquet in their backpack) and asking them if they would like to play sometime. There are also teams one can join(competitive or less so), tournaments, for fun social groups. Its been very wonderful.
