Catavarie is correct. This has been discussed before and rejected.
On the face of it, it does sound like a good organization tool. However, because many of us do travel quite some distance to hangs, it's good to keep them all lumped together.
I've traveled from Florida to Texas for a hang and other Floridians have traveled to Virginia, Missouri and Tennessee that I know of. Tennesseans and Canadians have traveled to Florida hangs and at least one USA hanger has traveled to Sweden for a hang. Hammockers know no bounds!
