The first game-in-the-sky will be tonight, Denver-Houston, with the blimp hovering over Florida's west coast. Those lucky folks in Tampa-St. Pete will get to watch Saturday's game as well. Then the blimp floats on over to Orlando. The TV screen is 70 feet-by-30 feet. No sound, though. Which is a real shame. ave you heard Bryant Gumbel and Cris Collinsworth?
