I did look at the websites for a dozen of the closest orchards to Boston listed on:
The only one I’ve found that seems to have them is Volante Farms in Needham, but when I emailed them they replied that they are not in season yet. Their season runs Mid-October well into November.
Everyone should try them! That are nothing like a Golden Delicious (which I find boring). They are both sweet and tart at the same time, very eatable with fairly thin skins, good for cooking, very disease resistant, and remarkably long lived in storage (I’ve read reports of people enjoying them one year after picking). In fact, they taste better with some storage.
