We just reserved a heritage turkey for Thanksgiving. If you're interested in doing likewise, it's definitely not too early to do so. A number of farms in Western Mass grow small numbers of heritage breed birds for just this purpose. We reserved ours from Wells Tavern Farm, which is just off route 2 in Shelburne. You can check CISA's database for others--just type "turkey" into the "Find it locally..." search box.
I have never had heritage turkey before, but I have heard that it is a gustatory experience worth having, juicy and supremely flavorful. Here's one good reason to look forward to November!
