That is odd that they did not want to investigate. That is a shame that he had to go like that, what kind of temps are you guys getting up there? I was looking online the other day for the weather where I hunt and it was up there like 109 or so and it gets like that every summer and I haven't noticed or heard of any issues with the heat. I would think they would be pretty tolerant to the heat, maybe not though, I know it gets colder up there too.
