I wait it out in any place that I won't get wet in. Last year at SFGAm, it didn't have any bad storm or anything, but for about 20 minutes it poured buckets, and by the Power Dive, a puddle formed, and then a pond formed, and right before the rain stopped, a lake formed. I saw some people run through it, and it looked a easy 6 inches deep.
The only time I remember bad weather, we went to the car. It wasn't because of the bad weather, it was because we wanted lunch! We brought food to eat in the parking lot, but we ate in the car. It got really windy, then lightning, then rain, and it stormed really bad for a little while. About 5 minutes after we finished eating the rain stopped, and about a hour later the sun was shining. Talk about good timing!
