First in a new, small series to populate a new public park. According to its website, "Rockingham Park at the Crossroads will be a local and regional destination for athletes, recreation enthusiasts, and park goers of all ages. State of the art facilities will serve as a model for modern park development and will captivate the interests of everyone who uses the park."
You're looking for a suspended bison tube. If you've seen this type of cache before, it will be pretty simple. If this is a first for you, it could be pretty tough.
This park can be very crowded at times, so use caution. Also, please only search during posted park hours.
