Wow! I feel like I just experienced the real-life inspirations for the vision of Liberty Street. In the past few weeks, I toured historic Philadelphia, visited Greenfield Village at The Henry Ford in Michigan
http://www.hfmgv.org/village/historicdistricts.asp, and then noticed the Liberty Street concept art in the "Great Moments with Mr. Lincoln: 50th Anniversary Edition" display case. All for the first time. NM and I were commenting on its similarities to WDW Liberty Square (also experienced for the first time in December) and noticing what a large space there is between Tomorrowland and Main Street. But, where would the parade go?
This thread and Jim's article just tied it all together for me. I'm having a historic moment. Thanks GC.
