I’m not sure how I made it out of my teens if he is correct. Spent a lot of time during summer break setting property corners in subdivisions being built while it was that hot. By setting property corners I mean using a hammer to put pieces of #5 rebar in the ground. I’ll grant it was work for 10 minutes take a break for 10 minutes but I was still out in that heat for 10 hours. When I wasn’t doing that I was in the woods or a swamp somewhere cutting line with a bush axe.
All of that was preferable to being on lake parcel doing a boundary at 8am in December catching an off shore breeze when it’s already in the low 30s.
