Alan,
I hope you don't mind other camping promotion in this thread.
Anne and I are camping at Indian Springs State Park in Flovilla on Memorial Day weekend (May 22-25). This state park is between Atlanta and Macon, about 10 miles east of I-75.
If you couldn't make the Springstream (like us) or just want to camp, feel free to join us. There were 12 25' trailer sites still available for Fri-Sun night stays as of yesterday, but no sites larger than that for that 3-night window. These sites are $25 per night.
Thanks.
