On those rare occasions when I want a used bicycle pump and/or a one-night stand with some random stranger of dubious background, I pop on over to Craigslist to see what I can scrounge up. One has to be careful when dealing with people online, and the only advice I can give is to keep track of which person you're visiting. Trust me, no one wants to walk out of their garage with a bike pump and see you standing there naked because you confused them with the person with whom you've set up a sex date. What's even worse is trying to explain to them, regardless of your mistake, why you would think having sex on their lawn in the middle of the day was a good idea.
