280 is a September 15th rifle unit. There are good elk and deer in that unit. The elk will be rutting but often quiet during the day. There is actually quite a bit of pressure in the unit from outfitters and DIYers, but it is also big and deep. Treat the trail system like roads. Get off them, and you could have a great hunt. Go DEEP and give the outfitter camps a few trail miles of room.
That is serious grizzly country. Keep that in mind.
