Ringgold didn't gain its fame for Parton's nuptuals there - but rather for its extremely lenient policy of allowing very very very young couples to wed with a minimum of such ugly details as "parental consent" and red tape. Lots of then-mid-teens got married in Ringgold, and it didn't matter what state you lived in. Instant license, hit the chapel, pay the parson, and you're off to the races. If you got married in Ringgold, it was usually because you were too young to get married anywhere else.
Uniform state laws changed all that, of course, but GA still has the lowest age-of-consent laws if I'm not mistaken.
