I was happy to see Northern Spy also but every year it's harder to come by. Baldwin too. I was shocked not to see Cortland. I live in MA zone 5 near New Hampshire line and both here and in NH it's a staple. A late apple and great for eating and pie. Eating Macouns the last couple of weeks though.
Well that's a great cooking apple, I grew one of those trees for a while. Most reported that it was too mushy to be included in a pie, but if that is the kind of pie you like then can be treated as McIntosh, etc.
