I've shot the Great Northern ever since they started, and I think all the UP SxS Classics except maybe one prior to that. The GN is a really good event. Well run, lots of vendors with nice stuff to look at (and maybe buy).

Shot Duluth for the first time last year. Not many vendors, and I didn't care for their 5 stand. No menu. That wouldn't be as much of an issue if all the traps were somewhere in your normal range of vision. But with a trap or two behind you and/or on the extreme periphery, you have no idea where to look for the target(s). And I can't hear traps when wearing ear plugs.
