Country Nate,
31 is an impressive number to a lot of Grouse hunters,
especially today. As you indicated it all depends on how much time you spend in the Grouse woods, in reality.
I average about 22 Grouse a year from many different coverts in several different states, never damaging any individual covert. This season was very good Grouse hunting here on the northern tier of Pa. January was cut short by 2 1/2 weeks for us due to some problems in the Churchill home, and we still ended up taking almost 20 Grouse. Hunting Sharpies on the prairie, is definitely a lot of fun, however I actually like walk up hunting in Scotland for Red Grouse much more.
