Sorry, no digi camera, Mike.
Took about 4 hours at 250(ish). After the first hour I started basting w/ the ( now boiled)marinade and used it all up by the end.
It was about 7 pounds of pork back ribs, a can of Guiness, half bottle of the Ras Sauce, maybe 3-4 ounces of vinegar, and a good coating of mesquite rub.
I was worried that I add'd too much vinegar( had a bad marinade experience w/ vinegar and steak, once), but I guess I didn't because it came out great.
