GERRY - The nice thing about winter in the southern states is cold spells don't last long. Up north they last forever as Charlie says.
January of '75, as a Junior in college, I was lucky enough to be part of an independent study group for people in my major. As part of the group, the advisor rented a 6-passenger camper on a Dodge van chassis for him, the 5 guys and three girls to "Visit" other areas. Like New Orleans, mainly Bourbon Street, Houston Space center, Gateway Arch in St. Louis, etc.
One of the people in the group made arrangements for us to spend a night with his aunt & uncle in north-eastern Mississippi. Was cold and snowy that night. From driving so late with all the lights and heaters on the battery was dead the next morning. Your's truly had the honor of using cheap borrowed frozen tools to tighten the fan belt while laying in six inches of snow in FOUR degree temps. I had my BIG cantilever tool box with all my good tools stowed for the trip when I was assured we wouldn't need it and to take it out. There was even a pair of gloves in it which would have kept my hands warm.
But that night, sitting on Bourbon Street in t-shirts & shorts sipping Margarita's I forgot all about it.
