Here is a pic of a recent MichLTC display in Canton, MI:
The large buildings from left to right are Chase One bank, Griswold Building, 1001 Woodward (all Detroit buildings) and on the right is a replica of New York's Flatiron building. The Detroit People Mover's elevated track is visible in the foreground.
This was a 10x15 foot display. MichLTC's display at NMRA National Train Show in July will by 30x40 feet. Nine other Lego train clubs from other states will also have displays.
