Yes, there are so many things we used to take for granted, fresh tomatoes etc. My grandkids don't even like tomatoes and I don't blame them! Too bad. But mangos in Oregon or New England are really pushing it. No way we could grow them locally. (I don't know where you are in New England but here in Portland we are about 30 miles further north than Montreal!) I really think they have to ripen at home over a longer period of time. As you say, probably picked very green in Mexico or wherever in the far south.
By the way, I was mistaken about the price here, My wife, who is the shopper, says they are only about .59 cents (not .89) each.
Well, this is an unusual thread for a XJW site. They probably think they'll all have a mango tree in there garden in N. Dakota in the New World!
