Grouse are found with boot leather, not the internet, Why would you think people who have scouted and sweated finding grouse coverts would give them away to someone who scouts with the internet. Now being new you probably don't know but grouse coverts are not given away readily especially to strangers because they can be shot out easily. You have been given areas to look at, the rest is up to you.
When you are up to your butt in alligators, it is hard to remember your intent was to drain the swamp. Stay focused!
