Google Earth has improved their service by offering historical imagery. Here's an example of how it can be used. If you open (and update) Google Earth, go to the Children's Zoo in Houston.

Perhaps this will be useful in seeing how much some of our favorite locations have changed since 1981-ish.

I looked through all the old forum threads, and this seems like the best place for what I want to do -- create a repository for all known newspaper/magazine clippings related directly to The Secret.

If I miss any that have been previously posted please let me know where to find them and I will add them to this thread.
First, the Cleveland Plain Dealer of June 13, 2004 -- the article celebrating Egbert's and Siskel's triumphant find in Cleveland (scanning credits to Egbert, I think)...
