My first (and so far only) time at the Animal Kingdom, we were planning on riding Kali
until we started to notice all the miserable-looking people, drenched from head to foot, slogging their way around the park, and realized where they'd come from. It was a hot day, but we were all wearing sneakers, I had a thin white tank top on, and we all had cell phones in our pockets that we didn't want to get water-logged -- a vote was quickly taken, and we were unanimous in not wanting to ride after realizing how wet we could get.
This time around, we'll be changing into our Tevas and packing ponchos so we can ride! I don't mind looking like a poncho-wearing dork, when the alternative is to spend the rest of the day avoiding air-conditioned venues so I don't freeze, and leaving soggy footprints in my squishy shoes.
