As expensive as tubes are getting, it's just not worth the trouble since I probably had 2,000 miles on the tire anyway.
If you patch your tubes, you have a good record of where on the tire your flat happened. Get two flats at the same patch (or an exactly equal distance from the valve in the other direction, you know just where to look for that little piece of wire.
Edit: I gotta start looking at the thread dates!
