Wetlook World Forum

They used to have a couple of other interesting events there as well.  Sometime in the late spring/early summer they held a water-ski show on Lake Lagunita called the Aqua Follies, and the Dollies usually managed to end up in the lake.  I also recall seeing a photo of freshman orientation being held at their olympic-sized pool, and the whole band jumped in.  Of course the Dollies, being part of the band, jumped in as well.  Either of these really would require a telephoto, as the crowds were large and to get a clear view you pretty much had to be up high, which was possible but only from one or two hundred feet away.  If you look like a college student you could easily mix in at the water ski show, but the orientation event probably required University ID.

I don't know if either of these still takes place, as I haven't been around Stanford for many years.  Worth checking out though - I saw the Dollies dunked at the Aqua Follies a couple of times, and they were about the hottest wetluck sight I've ever experienced in person.
