Ground Storage Tanks - Something Old(ish); Something... Older

We went down to Austin and looked at a couple job sites to bid.  One was for a rehab of a 200k gallon Ground Storage Tank (NOT this one....).  Just beside the tank for rehab was this 200k gallon GST that we built a few years ago.  Paint looks JUST as good as it did the day it was painted.  Thanks, Jay!
