How far north to be reasonably high ground?
30 miles west actually, in St. James Parish. At least it looks like that on the map I found. It's largely undeveloped now. The land is owned by someone surely...but being rural land it's affordable from an urban homeowner's perspective. I'm sure if I owned 5 acres that used to be worth $200k but was now worth millions to the developer that wants it...I'd sell! Especially under the circumstances.
Arkansas.
