A neighbor had a large apple tree (climbable) which had a large-yellow-green apple. They were delicious, as I remember them.
Not the same as the golden delicious apple in the stores now, not sure what the type was.
The neighbor complained to our parents about our climbing the tree, but not about the apples. He would let them drop and sweep them up, I think for compost.
I never saw an apple tree that large again- no idea what it was.

We also ruined his honeysuckle flowers. We would bite off the tips of the flowers and sip the tiny bit of nectar. Now that did get retribution (swatted with a broom).
