Why would anyone want to spend 2/3 days away from family, friends, a comfortable bed to be in a cramped (even FC) space with barely tasty food just to be able to do it again next year?
This sort of logic could be applied to many hobbies from hunting to skydiving.
I personally like to transit through LAX so that I can run down to In-N-Out Burger for a fix, and SFO so that I can stock up on decent sourdough bread.
