After having six flats over the summer (three on single day in July), I'm happy to report that I haven't had a another one since August. Seriously, I thought it was time to replace my tires (a Big Apple and a Marathon)-- so I ordered new ones, intending to change them next time I had them off the rims. So now that I have the new tires ready to go on --one in my desk at work, one in my basement at home-- I haven't needed them. Not that I'm complaining, you know.
As with flipping a coin, you can't use past results to predict future results. Your chances of getting a flat are the same today as they were yesterday, regardless whether you got a flat the day before.
