AVA Data
[edit]Hello. Actually, I was not so fortunate as to find files containing the AVA data. Instead, I went back to the Code of Federal Regulations, which defines the boundaries in terms of roads and rivers and the like. So, in the case of the Lake Michigan Shore AVA, it's the course of the Kalamazoo River until it intersects with a certain railroad...and then following the path of that railroad until it intersects with another railroad. And from there to the state border. So, I took the GIS data for the railroads and river and cobbled them together into the AVA shapes.
Hope this helps.
