I don't think it's the 90º+ heat that's keeping people home because it started when the temps were in the 70's.
The traffic in the shopping areas on Long Island is excruciatingly light lately. Except for during rush hours, you can breeze where ever you want to go. This is a startling change for us Lawn Guylanders who are accustomed to waiting for every traffic signal twice. I wonder if it has anything to do with the $4.29/gal for regular gas prices and/or the fact that everything has gotten a LOT more expensive. Or maybe everyone is at the beach (even though the water isn't warm enough to swim in just yet.)
