C.B. Cameron Park is home to the North OKC Soccer Club. It is a 65 acre park dedicated to soccer in OKC. There are 17 soccer fields (various sizes) and four practice fields. All field use must be permitted and scheduled through NOKC Soccer.
This waymark is located in Field 4. Once entering the park, follow the drive along the north fence. Field 4 is on the right.
This park has no listed open/close times. I had been here twice before to try to get this, and the gate was locked. It was finally open this morning. So don't expect to get this your first try.
I used pen and paper to list possible palindromes, then used Google maps to try out the coords to see if they might be in an accessible place and maybe even interesting.
