When I was stationed in Texas in the early 70's, my family and I rented a house that didn't have air conditioners, only two large swamp coolers. When they were on, it was like living on the beach with a wind blowing fresh moist air. The fans in each were at least 3' long and only had one speed - high. Never thought I'd hear that device mentioned in a crappie forum! Brings back memories of tornados, red dust storms, armadillos and heat waves of 100 degrees for 5 days straight! Those were the days....
