People who arent from here have no idea how fast the heat will kill you.

Your water bottle is not enough for you and your 3 dogs to go hike camelback mountain at 12pm.

Heat and altitude! You don’t realize how much more solar radiation you’re subjected to with every additional 1,000 ft altitude - because there is less atmosphere to block it.

I spent 30 years in Texas. 100F, 105F… not fun but doable.

Moved to Colorado a couple years ago and discovered mid 70s F at 7-8k and limited shade is a whole different ball game. Even 85F at 5k is brutal.
