I technically know how to shift a motorcycle. Been almost 50 years since I drove one myself, but even without the heat, in Dallas Fort Worth, it's dangerous enough in a solid metal pickup. And yes the humidity today is horrible, it got to 104 in Fort Worth and the Temperature Humidity index was probably 112. Central Air is supposed to be installed saturday. I can't get the living room below 84 right now on a large portable ac, but with the fan from my window unit bedroom I can house humidity down to about 55%. On the portable alone it was 77% humidity in the living room when I got home from pond service calls.
