That's a fair point.
If some kid was saying, "nah, I'm staying up north to play because I can't stand the heat and humidity down south," I think it would be fair to question those comments, too.
Wanting to do it and being able to do it are two different things.
I hate cold weather and given a choice will pick tropical weather 10 times out of ten.
Yet my entire military career was spent in cold weather bases. Questioning someone toughness because he doesn't like certain type of weather is just stupid.
