Ever had last minute bad luck?

I was just getting my gear together and doing maintenance on my bike for the Harmonie Hundred tomorrow. The last thing to do before showering and going to bed was to just air up the tires just in case I forget to in the morning. I'm pumping up the 2nd tire and "POOF" air starts blowing out around the thumblock. I guess I should just pump it up with my minipump but I going to see if Wally World has a pump for presta. Couldn't be any less quality than this Nasbar model than went kapoop.
I'm glad I didn't wait until I got to the event to pump em up!
