Amuse bouche: Any escape from the heat?

This week has been a jarring reminder of the wickedness of Houston summers. Is there any way to escape the heat? Can't someone invent some sort of cooling unit that will allow us to enjoy patios even in the throes of this swamp, like an air conditioned or ice-lined shirt? Apparently none of that is in the cards in 2009. So that means we're left with the traditional standbys: cold beer in frozen glasses; bottomless pitchers of margaritas; chowing down on Five Guys with your feet dangling in the pool; and doing anything possible to avoid setting foot outside to begin with. Summer is a great time to familiarize yourself with how to navigate downtown Houston's tunnel system. Anyone with novel ideas on how to beat the heat?
