You are looking for a bison tube hidden near the playing fields.
Parking is available at the cache spot and the playing field opposite is great for younger children.
The cache is on flat level ground, but you will need to be of a certain height to retrieve.
Dogs are not allowed in the playing field, but you do not need to go in there to retrieve the cache, so this can form part of a nice circular walk with your favourite canine friends.
Congrats to the Marauding Millars on their first FTF!
