Yes, I would like to hear from them too!
It looks like La Mayora has some interesting research topics and I might try reaching out to one of the researchers, especially if there is nice experimental plantings to possibly check out. I'm mainly looking to find some other Annona farmers as it looks like the Cherimoya festival is not happening this year.
I joined the CA Cherimoya assoc. a couple years ago and am hoping to hear back from Dario , who might have some connects.
Thanks again JF.
