I found these photos on Flickr. I have yet to find the story behind it other than this a fully-functioning model of a Skyway-type ride in this person's backyard in San Diego. Watch this thing in action here. This video clip takes you on the miniature ride. I imagine they strapped a digital camera to one of the gondolas.
Lesson learned: If Disney rips out your favorite ride and gives you really lame excuses as to why they did it, build your own version behind your house.
One time a buddy of mine and I saw Marty Sklar at Epcot. We went up to him and said, "we are backyard Imagineers". He looked at us like we were nuts and said, "never heard of that. What does that mean?"... "Uhhh well, you see, Marty, it's when kids like us make things at home that resemble what real Imagineers do in the parks." He had a look on his face like, "oh brother".
