Last Summer I visted Cornwall in U.k, visted 2 Breweries, 1 Cider farm and 2 Vineyards.
What about ICB brewery tour , Les you might be able to help.
Just an idea, but I think with enough notice at least 6 months. We could go to some beer region, like Munich,Plzen,Yorkshire,Scotland,U.S, etc
Might be able to get group discount and escape from wives or girlfriends.
