A wall has appeared around the favorited old Tom Sawyer's Landing area at SDC, complete with teasers of a wet ride to come. You can see some photos of it here: http://www.sdcfans.com/gallery.php?id=8
The Balloons and the carousel currently residing in the area are set to move out to the Grand Expo, close to the waveswinger.
If you think this will be anything like the Splash Battle at DW, you're wrong. DW's variation is cool, but this will be much more thematic, and IMO, will have much cooler amenities. The concept artwork (http://www.sdcfans.com/gallery.php?id=7
) shows off a lot of cool stuff like a little fort jutting out into the pond with cannons sticking out of it, and I'm sure the area will be packed with all sorts of cool oddities and gimmicks like the rest of the park. In fact, the ride itself is only part of the project; with it will come a revitalization of the entire area, bringing Tom Sawyer and his companions back into the SDC scene.
I'm REALLY looking forward to see how this turns out, I'm thinking this will be a true test of SDC's brilliant thematics team, which has done some truly amazing, Disney-quality stuff over the years.
