DSIL gave The Colonel and I permission to pick the fruit (by the looks of the tree some of the neighbors had been helping themselves to it as well).
The ripest tangerines were higher up in the tree (apparently the neighbors could not reach them so they tree-ripened longer which made them sweeter). The Colonel and I used a ladder to pluck the upper tangerines.
We must have eaten two or three each as we plucked away. We ended up picking about 40 of those little orange balls of Florida sunshine. We gave half of our harvest to our friend Louise who said they were so good she might not share them with her husband.
I don't have a fruit tree in my yard yet, so it sure is nice to know someone who does and is willing to share the fruit. Being related to the tree owner helps too. Thanks a bunch DSIL.
