Even here at SFist there can be times when a lull in our social lives has us humming "Another Saturday night and I ain't got nobody." Luckily, Craigslist is here to save the day. Just a quick sampling gives us an early morning run, learning to ride a motorcycle, climbing, b-ball,, soccer, or maybe earning some karma points.

And just in case you need space for that quick game of bridge, Craiglist can come to the rescue.

If you don't mind doing a little more legwork then browsing some of the forums or the event calendar can oftentimes have amazing results.

Of course, by the time that we've done all this browsing, reading all those forums and staring at the event calendar till we forgot what day today is, well, we will probably just drop by Amoeba, buy "Another Saturday Night" and put it on infinite repeat. Or until the lady next door gets truly fed up with us.
