Yesterday I was at the local Ingles supermarket and I noticed they now have 10oz Red Rock ginger ale in 6-packs, in addition to the usual 4-pks of 12oz glass.
The deli bottles were produced at Tri-City in Johnson City, TN - they've picked up the brand since Union City shut down.

I also saw the deli Red Rock in Ingles. Tri-City is also producing more since Sundrop of Concord NC stopped bottling (all they produce now is BIBs).
