Park in the parking lot that is north of the football field. Walk behind the north-east side of the football field and you will find a trailhead behind the scoreboard. The trail will lead you right to the cache. Please cover the cache well so that it won't be found by muggles.
Please remember that the "swag" items inside the cache container are trading items. If you take something, you must leave something of equal or greater value.
Congratulations to Scooba for the First To Find!
