Heritage turkeys

I read an article about Heritage turkeys in Fortune. These turkeys take longer to raise than the Large White turkeys that make up most of the turkeys eaten in the U.S., especially at Thanksgiving. But Heritage turkeys taste better (more dark meat...mmmm), and the way they're raised conforms to the principles of the more ecologically-concerned.
Heritage turkeys almost went extinct, but ironically, they've made a comeback because organizations like Slow Food are encouraging people to eat them. That in turn means more farmers have economic justification to learn how to raise them.
Heritage turkeys cost more, but if you're only going to prepare a turkey once a year for Thanksgiving, seems like a worthwhile cost premium. Here's a list of farmers and mail-order sources for Heritage turkeys.
