Looking for 2014 Rally parking [2-3 weeks]

Morning USCA Folk,

I'm planning to attend the USCA Rally in Hardeeville and I'm also planning to attend the BMW RA Rally at Barber Motosports Park at the end on May. I'm looking for a kind soul that will let me park my rig on a trailer in some semi-safe place for the 18 days between. Yes, I'll be coming with a trailer, I prefer to drive to get someplace and then ride when I get there. Let's not open that old chestnut. I know, I'm an aging whimp.

The ideal place would be someplace between Atlanta and Hardeeville or Atlanta and anywhere on my way back north to Minneapolis, say Chattanooga or Nashville. Anywhere around that area would be a huge help as I'll be making the trip twice within three weeks. Thanks for your consideration.
