Lost Badlands Superday backpack (ellensburg)

I left my Badlands Superday pack sitting on the side of the road when I was deer hunting up the Reecer Canyon, out on the end of FR 3521.
This was on Saturday, October 14.
It's almost brand new, mud brown colored, and has some of my personal hunting gear inside that I got from family and would love to get back.
Call or text if you have any information.
I would really appreciate getting it back.
Thanks, Cal
