Just visited the International District/Chinatown tree, and it’s nearing peak ripeness, maybe one week to go before they are as ripe as the one @ramv posted above. With recent pruning and other people already reaching what could be reached from the top of cars, I was only able to get a single almost-ripe fruit from the top of my car, but collected some seeds from rotten ones on the ground. The tree is loaded high up in the canopy.
I went ahead and ate the one I picked, it was already quite sweet but still a little more tart than this tree gets at peak.
