You are sooo right that it is hot. Don't let MikieC make you feel like a sissy. You're not are you? He is just tougher then the average transplant.
A swamp cooler is an evaporative cooler. Inexpensive to operate and relatively effective as long as the humidity is low. Worthless when it climbs. If your DaddyWarbucks like Eric (how many guys have a Cobra and a Vette) and can afford the big energy bills, go for the air conditioners. Being bucksdown, the swamp works for me. Started working on my car at 4 PM yesterday and the garage temp was 82.
