I wish I had seen this thread before I started my build. The information on the glycol setup would have saved me a ton of research time! I ended up calling kegworks and working with one of their corporate sales guys. He was a lot of help, but had I seen this, I would have used the company in Annapolis. I used to live out there and know the area well.
I saw you mentioned Lures I used to go there occasionally as my oldest daughter went to Indian Creek, just down the road. Used to go to Ramshead when I was riding my motorcycle, just to pose though because I never drink and ride.
I also really like the FOB idea and plan to do the same.
