Living in Florida gives me a chance to see the more sedate side of Florida rather than just Disney and Busch Gardens and the like. A lot of the downtown area of Dade City, in central Florida, is little antique shops. Most of them are in older buildings that are sort of dark and you just know from the get-go that you're going to find a treasure.
A lot of the shops here house a huge variety of antique dishes and other glassware, as well as some old clothes, wedding dresses, and books, and there is at least one shop totally devoted to quilts. There are no high rise parking garages but there are some quaint little tea room type places, also full of antiques, that you can stop in during your day of shopping for some soup or salad or a little sandwich.
Lakeland, about 20 miles south of Dade City, also has a respectable number of antique shops in their downtown area, which even has its own antique name, Dixieland. Some are even two-story buildings with antiques upstairs and down with tiny little stairways to get you there. Again a lot of really nice dishes and glassware, some small furniture, and lots of fun looking. I know all the readers of http://www.iantiqueonline.com would love central Florida's antiqueing districts.
