I have seen more than a couple of hot topless chicks at Barton Springs before. One time a hot topless girl inspired several other otherwise insecure chicks to take their tops off. These are sorority type chicks we're talking about here. That day was glorious. If it had been an only moderately hot girl at first, the other girls would have just snickered, which is usually what happens at Barton Springs when a chick goes topless.
I went to Hippie Hollow one time and there were no people there at all. I was at least hoping for something weird to happen.
One other time I was on Lake Travis on a boat, and we passed this fairly large boat with lots of naked people. It looked like some kind of swing party on the lake type of deal. There were definitely lots of hot girls, so we kept swinging back by as often as we could. The only problem was that some of the women were slightly older and looked like leather, and there were also naked dudes amongst the girls.
Another naked story was during Spring Break a couple years ago in South Padre. My friends and I went down to the dune part of the island, where there are no hotels and stuff, and we came upon 5 girls (2 hot, 2 okay, 1 so-so/blah) from Michigan who were sunbathing nude, so my friend just walked right over to them and started chit-chatting about this and that, and somehow we didn't seem threatening to them, so they just stayed naked for the entire time we were there. It was so weird. It was not regular Spring Break flashing girls gone wild type nudity. It was all-out nudist nudity. We barely even talked about the fact that they had their clothes off, either. And we ended up not hooking up with any of them, either, which was even more bizarre.
Public nudity is such a weird thing. It is totally unlike regular nudity. If I see a naked girl in our own little space, that is exciting. Same goes for nudity on tv or movies- it is exciting. But exhibitionism in public is not merely exciting. It is a special treat you don't have to work for. It is kind of the same thing as going somewhere and undressing girls in your head, but it actually comes true in these cases.
So the moral of all of this is that more, not less, hot girls should be naked. And there should be a renaissance at Hippie Hollow to get rid of gay and fat dudes (guys in general, actually) and replace them with only the hottest of girls. What would it take for that to happen? Maybe if there was a rumor around campus that Matthew McConaughey hangs out there. The girls would flock.
