It is hot. But I'd live in hell and rent out Texas before I'd move to Michigan.
Seriously though I was working out some wood shafts yesterday for my new Primal Tech two piece bow with my local arrowsmith/string builder/champion archer friend and I shot on and off for hours as we visited and he worked out shaft length until the flight was right. It was hot. His shop isn't air conditioned and neither is his outdoor range. But some water and limiting time in the direct sun vs shade, a decent breeze outside and a fan in the shop. For me it was comfortable enough. But real hot weather hasn't hit yet. It was only 105 yesterday.
For the record he did a great job. I brought the test arrow home and stuck a broadhead on it for the real test and shot a few this morning. From 15 to 25 yards those pinwheeling fetching flew perfectly straight down to and on target. Shooting in the heat ain't but a thing if you really wanna shoot. You know, instead of looking for a reason not to.
