Not this year, but a couple of years ago when I purchased a new bike, I had three flats within the first 4 days of my purchase. I quickly got sick of it and purchased a set of Specialized Armadillos for my Allez. Goat heads are numerous, but around here, we also have an added problem with the amount of sharp rocks and objects pushed to the bike lanes and curbs. And the chipseal that is favored for most roads is extremely harsh on tires and riders.
