THOSE are the areas to concentrate on. they sound good, very good to me

UGLY man UGLY stuff
Nothing is " unhuntable" , there is alway a way. Get into these areas hard, and look for anything inside them that may open up a bit. Look for big trails - mature bucks use big trails inside the bedding area. Look for trails than span the length of the bedding area or may cross between two bedding areas.
Look for scrapes around the edge of the thick stuff and play the wind RISKY. Big bucks don' t like to exit a bed with the wind at there backs - if you play it too safe you may strike out.
Forget about rubs, cant hang them on the wall....LOL
Lots to say lots to say but I am out of time
Good Luck
