- The Windows of Main Street: Along the quaint American street, you will notice that nearly every window is decorated with a title. Each and every title on these facades is significant in that it lists, often cleverly, the name of someone involved with the planning, imagineering, or building of the Magic Kingdom. Keep your eyes open for Walt's name, and his father, Elias. Here is a link to many of the windows and explanations for their significance: http://www.disneydispatch.com/content/columns/the-626/2011/03-the-windows-of-main-street-usa/
- Street Lamps: Many don't realize that the length of Main Street represents a timeline through American Industrialization. Look at the street lamps when you cross under the railroad, and keep watching them until you enter the central plaza of the Magic Kingdom. You will notice that the lamps turn from kerosene to gas to electrically powered as you progress through the American Industrial Revolution. You will also notice that the architecture of many of the buildings follow this trend by turning from brick and wood to painted steel.
- Popcorn Stands: Again upon crossing under the railroad bridge at the entrance to the Magic Kingdom, take a moment to enjoy the air. Notice that the first smell to hit your nose is that of popcorn. Walt wanted this to be a subtle reference to the point that his park was telling a story. The popcorn is meant to evoke memories of childhood movie theaters.
- The Emporium: Although The Emporium has become synonymous with just another retail location in Walt Disney World, one can actually glean charming and rich knowledge about the "imagineered" history of Main Street USA. You will notice that moving from south to north, the family who is responsible for the founding of this establishment began with one small room on the corner, and expanded several times (sometimes hastily) to grow their shop as American Industrialization allowed them to more efficiently market and sell their products. Look closely, and you will see boarded up walls, family portraits, and quaint shop windows which all change to steel hooks, shelving units, and fancifully decorated rooms (such as the princess room).
Take time and slow down while you walt down Main Street leaving the park. The best time to appreciate all of these things is at night, after the park has closed, and most people have left. You can stay for about an hour and meander the street, enjoying the romance and ambiance, lighting and ragtime that join you and sing the gospel of Walt and his America.
