I've just heard some assertions that the blimp does not, in fact, start appearing on opening day. Some of my sources seem to remember that it doesn't appear until later in the summer. Others distinctly remember it being present on opening day.
If the former is indeed true, this might be a really boring web page for the next several months. Fear not; I am committed to providing a daily dose of blimpy goodness, even if this means getting really repetitive and ridiculous along the way.
Countdown: TWO DAYS UNTIL BLIMP, HOPEFULLY
