Ontario's Old Mills
on Sep. 10, 2012
A great resource for photographers interested in old mills. It is simple and easy to use. It is very thorough as well and lists a much greater number of mills than other resources that I have seen.
The only downside is that there are a few errors in the book - the indexing in the pdf is a bit off and the directions can be a little misleading. But overall it is a great resource.
