I never did locate the exact site of Ft. Green.....It was used for a small amount of time, and I believe, just a fortified house with militia...and might have been reactivated during the Civil War with Union sympathizers.
I have some drawings with Ft. Clinch diagrammed with relation to the lake.
There was a blockhouse a little ways from Ft Chokonikla...I'm not sure who owns the land...I need to get out my maps and narrow down the parcel.
I've never heard of anyone ever finding Ft Mendo...I have one map that shows the S/T/R that it is on in the platt.
I would go with you if you have permission on any of these....If you run into any roadblocks with a landowner afraid of letting someone on their land with no insurance, I can take care of that.
