We always like to push our weekend caching well into the evening even after the sun goes down. Well, having done most of the caches in Houston, we spent one day going after some local letterboxes. We pulled into the parking area for a dog park and proceeded to find 2 letterboxes just into the woods behind the park. We were signing the last log and we heard the Sheriff announce over the loudspeaker that the park was closed and we must leave immediately. Well, we looked over and he was sitting right in front of our car (the only one left) with his lights blazing. After a few minutes walk, we approached the cop and he asked where our dog was. We told him we didn't have a dog with us. He then asked why we were parked at the dog park without a dog.
Barely keeping a straight face. we explained letterboxing. We also explained that we had looked for a sign at the entrance stating the park hours, and didn't see one.
Anyway, the guy was really nice and let us go on our way, but I just know he was running our plates through the system....
