When going to IOA, I always get soaked from riding lots of times on Bluto's Bilge Rat Barges - wear tevas, quick dry shorts (with built in undies ), quick dry t-shirt - after I go to Spiderman to get dried off - that way, it is an indoor dryer as opposed to outdoors
Last December, I literally got soaked on Jurassic Park and since it was my first time at IOA, I didn't know this would happen and it wasn't warm enough to wear shorts, so I had on jeans! It was pretty bad and I was miserable!! LOL This time around, thanks to these great threads, I have already bought a pair of cargo shorts and some sandals!! There is nothing worse than having to walk around a park in wet jeans!!
I just went to the local Army/Navy store to buy a sleeping bag and I saw some of these Quick Drying UNDIES!!! So for us women who can't just wear their bathing trunks (like the men) this may be an option. They seemed to be inexpensive, $4.99.
By the way, there was also a pair of underwear there that said on the package, "21 days in Europe, 7 countries, 1 pair of underwear". EEEWWWW
