It’d be a long drive, but:
“KY Parks Offer Discounts to FL Residents for Irma”
At check in, refer to code PR25 and show your Florida driver’s license.
I believe this is only for lodges and cottages. More info. at the link.
Disclaimer: I am not associated with KY state gov’t or the parks in any way. Except for a few visits. :-)
Could Pres. Trump order that National Forest campgrounds and such be made available at, say, 1/2 regular rates, for up to 2 weeks, for FL evacuees?
