I'm not that far south in Texas, but I have been to his citrus events before.
He is a great guy.
Back before Texas really clamped down on county based restrictions a few years back, he brought a cultivar to me(er I met him halfway) on his way to North Texas.
My understanding is that he is no longer able to sell outside of his county for the time being. I could be wrong, but I think that is the case....
But I went ahead and sent him an email. If he doesn't have one, maybe someone else does that he knows..perhapse outside the quarantine restricted counties.
Anyway, John is a cool guy.
