I would recommend practice shooting in windy and rainy conditions at moving targets.Boo don't stay still, they seem to be always on the move. Be ready for shots out to 60 yds. The weather changes quickly so have gear and a good pack. Get in condition for lots of hiking. Research your outfitter if you are using one.Be ready to hunt hard as you never know if you'll hit a migration or be hunting singles or doubles. Be ready for a great time.
I went in early sept. last year to northern Quebec and it was the hunt of a lifetime.
