Marceline's Main Street is actually N. Kansas Ave. The few blocks that run though down town have been renamed "Main Street USA."
Check this out, they even have an Emporium. Just like in the parks!
I wish I could park my mini-van at the Magic Kingdom's Emporium so I wouldn't have to take all my souvenirs on the monorail.....
And here's the old Uptown Theater!
You can't go 5 minutes in Marceline without seeing something dedicated to Walt Disney or hearing a train.
You can tell that Marceline is responsible for Walt's love of trains. Like I said before a train runs through this town every 5 minutes. The Walt Disney Home Town Museum is even in the old train station.
(And in case you're wondering this train was never part of the Disneyland Rail Road.)
