Didn't want to test things commuting today so if it's still holding air when I get home I'll try to put in some miles.
Bah! Only the 4th and already behind. Better get riding to catch up.

I should have been more clear when I said to check the tire for objects... you check the INSIDE of the tire with your fingers to see if you can locate the culprit. Most of the nasties that cause flats wear down due to road friction or hide somewhere, but they can often be found on the inside of the tire.
Maybe you already know this...
Oh, btw, I patch a tube multiple times, but about 3 patches is the limit.
