Over there is what I think you mean. “Up there” sorta implies Yankees and we’re definitely far from it.

LOL Old habits die hard. I'm on the extreme southern tip of Texas;
everything is "up there" from here and some even consider anyone above the Nueces river as Yankees.....but not me

Whitewings have slowly migrated north. My son lives in Houston and tells me they now have whitewings; never in the past.
The population has exploded, thanks to the drug cartels making Mexico a "no travel" zone. They used to slaughter whitewings down there prior to the drug lords. Our population has exploded here. Guess that is the silver lining everyone speaks of.
I have a friend who owns a lot of land along the Rio Grande and he puts on several catered hunts every year similar to the owners hunt you described above, but open to the public. A bit pricey, by old standards, but he "throws the house out the window" as they say across the Rio. Big BBQ and lots of grain fields draws quite a crowd. After whitewing season ( two weekends early Sept.) He opens the farm up to "lease" members w/o any frills for the dove season which runs a couple of months, I believe. Not a bird hunter, so not well versed on seasons.
The ring necks are relatively new "down here"

and are considered invasive so not regulated here, either.
