There's a meat locker at the Last Resort down on the Tucannon. On the off chance you're hunting off of the 40 road, it's not a bad drive but it's on the opposite side of the unit from Asotin. Good people down there.
It might be a shorter drive down there from where ever you'll be I guess. There's a road off of the Mountain/40 Road that will take you to the Blind Grade. Blind Grade takes you down to the Tucannon and the last resort is immediately on your left at the bottom of the grade. The name of the road off of the mountain road escapes me. Sorry.
