I started a website based on the need for information like this! In the forum at http://northtexasvegetablegardeners.com ... ?board=6.0
you can drill down by county, city/area. The idea is that each store will have its own thread, and users will comment on what they like/dislike about the store, what they have in stock, how knowledgeable they are, etc.
I hope this will provide some usefulness for some people, because I've spent some effort on it so far. Check it out and give me some feedback if you will please.
