For years my dog and I have been jogging this trail around the Hartridge subdivision. I have often thought "that would be a good place for a cache." Please stay on the trails as you go to this one. If you park near the corner of Pembrook and Coventry you can go get the Castle park cache and then follow the paved trail to the morning jog series. The paved trail is about a 1.3 mile loop back to the park.
On your way up toward the water tower there is geo-trail off to the side. Follow it. BYOP...You might need a tool to extract the log.
