Fancy a swim? Though swimming in Beebe Lake is not allowed and ill-advised, you could go for a swim in the nearby Hellen Newman Rec building which overlooks the lake! Though you won't be able to swim if you come off-hours, you will find it this area a lot less crowded and with a lot more parking.
You are looking for a 3-d printed micro cache with a unique shape. Please replace as found, BYOP and maybe tweezers. Don't try to go down the hill behind the parking lot.
