specifically,
besides cultural issues and travel requirements,
I think very specific areas in the US are more than adequate.
notwithstanding the taxes and governmental issues associated with these.
After all, there are places in the US that are completely uninhabited but perfect for growing things.
Quite a few places come to mind if you just look at enough different maps. Water, people land density etc.
Do you even have to own the land to grow crops on it? Those Mexican growers seem to grow pot just fine on federal
land, why can't you do the same with veggies?
