These days, both islands make me a bit sad. Walt's original idea for Tom Sawyer island was to make it a place where kids could play, climb and explore. I was lucky enough to visit the DL version when I was 8. It was a little boys dream. There were rocks to climb, a cave to explore and all sorts of adventure to be had.
Much of that is still there, but what makes me sad is what the lawyers have done to the place. Any place where a kid might possibly fall and scrap his knee has either been blocked off, removed or made "safe" by adding paths, stairs and warning signs. Gone is the sense of climbing and exploration. It all feels so controlled now.
