Other than the shop windows showcasing Halloween merchandise, the only fully decorated section is Main Street itself.
We LOVE strolling down Main Street on the non party nights and looking at all the jack-o-lanterns, they are all different and some are quite cleverly themed. Sports items at Casey's, ice cream themes at Plaza Ice Cream, etc. Especially enjoy finding the "restroom" one usually located atop the fire station, we look for it every time we are at MK this time of year.
