There's a butcher shop over in Frankenmuth (MI) that professes to have something like two hundred varieties of brat, I think I may start to work my way through the role call this summer. Or would that be "roll" call?
We spend a week at Lake Huron where I will be away from my normal grill but, there's a 22.5 standard there, unless my brother decided there's some reason to change it.
If I owned a pickup truck I would load my double up there! Pictures to come some time. Not too long, I am very happy with my set up, need to finish the matching patio bar!
