re: Where is a good place in Louisiana to retire?

St Francisville is cool, but not retirement material location. And it's poorer than you might imagine. It's a place to visit, not necessarily retire to. The hospital there is more of a clinic. So good luck with emergency medical care.

I know you said NOT Mandeville or Covington, but that's probably really the best choices. Yeah, you'll likely have to evacuate if/when another hurricane comes along (not in Covington probably), but just how often would that actually happen? And you're close to good/decent healthcare (it's not the Houston medical corridor for sure) and social activities of which there are lots and decent food/restaurants. There's not many safer areas in the entire country, not just Louisiana, than Mandeville. And if you travel, you have three airports from which to choose.
