Any riders near southeast Georgia?

Hi all and Happy New Year! We are in Folkston, SE Georgia and looking for other long distance trail riders. I am presently doing basic training for Mariah, my 12 year old bay Arab mare. She is a solo horse since late 2010 and would benefit from training with other horses before we compete in her first endurance rides later this year. We have visited General Coffee State Park and Cary State Forest for potential wonderful trail training. Anyone ride there? They both look great!
Thanks ya’ll
