I worked as a roofer for two weeks in August in Alabama. That was enough.
I worked for 10 years as a lineman. When the bucket truck could reach it was just hard work. But when you spend day after day, week after week, climbing utility poles on a set of hooks, hauling wire strand up, pulling the fiber in and pulling the lasher, it was brutal. Especially in the south.
But the hardest work I ever did was as a land surveyor. I was a rodman. Mainly what that meant was the instrument man set the line, you got out a bushaxe or a kaiser blade and cut line. It needed to be about 10' wide, and high enough that nothing blocked the view of the instrument. And there was no deviating from that line. We worked mountains, swamps, and some of the thickest overgrown kudzu thickets you can imagine. Chainsaws were an occasional luxury, when the bigger tree was close to the truck. But when you are 4 or 5 thousand feet from the truck, you took turns with the bushaxe. Snakes, alligators, yellow jackets, gumbo mud, mosquitos, deer flies, beaver dams, a few wild hogs and one brahma bull were all just part of the fun. If the line went through the water, you waded. If it went through creeks, you waded.
