We have chosen locations for caches where it is safe to pull off the road within a short distance of GZ. Under NO circumstance should driveways and gates be blocked or used for parking. With nearby property owners in mind, these geocaches have been placed out of view and away from private residences, so as not to cause alarm. Please be mindful of the local community, and have a friendly chat with them if they stop by.
