I've never ridden Kali, but I have done Popeye's and Dudley Do-Rights at IOA in february. (64F out BTW)
I plan on riding Kali come Februay, my strategy includes having a change of clothes and a beach towel waiting either in a locker or with a non-rider.
I was not aware that they offered a heating/drying area, thanks for the tip!
Ideally, if the weather is warm, I will go ride Kali in the morning, then scoot over to Blizzard Beach, which I would really like to see.
