The one on the left, is a wild #apple tree. Picked it on the road. There's no field, no building, just an apple tree on the shoulder of the road. 

The one on the right is $1.50/lb from the store. I like the wild one best. I'd like to graft a piece of this tree, it's bug free, tart and crisp. 

My orchard was bare this year, but an unloved orphan on the highway has such a tasty apple
