7 vines? Maybe a single large beer, but if you drink a beer per vine and it only takes an hour to prune, you might get sloshed. LOL
Sounds like fun. If you get done, come on up. You can help prune a few thousand vines in the 2 feet of snow on the ground in the -20 degree wind chill outside today! Myself, I am waiting another month to start and will still be in snow!
