FWIW:
There are no natural lakes in Georgia. Most of the land immediately surrounding the large lakes is owned by the Corps of Engineers, and is basically a long series of connected parks popular with the locals. There is, of course, almost-but-not-quite zero security present at these parks, little more than entrance-fee collectors where they do exist, along with an occasional ranger. So, personal security is entirely up to individuals.
GA is quite friendly to both concealed & open carry of handguns - except for anywhere hinting of government property. After much legal wrangling, most non-building government property has been declared “weapons carry” friendly, but still kinda tense. CoE property is the remaining popular recreational area where it’s very reasonable to want to carry defensive weapons, but remains flatly “gun free zone” (likely wildly ignored).
Hence the interest in persuading CoE to end the gun ban. It’s only gov’t property for maintenance purposes, having nothing to do with military use, and having practically no active security. Georgia’s largest domestic gun rights group is doing well to get this resolved amicably - and soon.
Dragging it out further, however, seems a resistance tactic. We’re 1 year thru Trump’s first (and hopefully not last) term, and the CoE wants to stall for what presumably will be another year. Not good. Trump needs to rattle someone’s cage - especially as there’s no question lots of otherwise law-abiding citizens are choosing carry over disarm, with no ill effects.
“....owned by the Corps of Engineers..”
The Corps doesn’t own squat. The people of these United States own it. The Corps is just the custodian.
