From Caldera? Hah, that's my home. I've spent a lot of time out in the fields working crops in the dead heat of summer. Even as a native, I'll admit it can get uncomfortable on the hottest days.

But as for Citadel, I recently went up there for their sporting events. I took part in a good number of the visitor brackets for fighting and other games. I had a very good time... and learned a lot from the whole thing.
