Any hot stories about truck drivers
Look at Cmsix's stories. I can recall one about a log truck driver, but there are others. I am not sure about the temperature in the stories, some are in Texas, so likely it is fairly warm.
Art Martin (http://www.asstr.org/~Art_Martin/) has a couple of trucker stories, as does Lasiter (http://www.asstr.org/~Lasiter/). Both authors write a lot of stuff which doesn't fit SOL's rules, so you won't find them here.
