So I discovered this pathway to Kelsey Creek when I came to do a community clean-up. I spent quite a while at GZ picking up trash. Then I got to walk through the creek bed to pick up more trash. I even saw an old car embedded in the side of the creekbed (Cool!).
You do NOT have to go into the creek to find this cache. It is a quick park and grab. It includes a wooden FTF coin and a couple other SWAG items. BYOP please.
