This bonus cache is associated with the "Notts Labcache Pool" Adventure Lab project, which is a "lab-art" series located in the South Nottinghamshire village of East Leake right in the CENTRE of ENGLAND and has been placed to coincide with the Notts Labcache Event #14 to celebrate the 300th Lab going Public.
If you would like to take part in the project and create a set of labs to join the series, or just have some background information, please contact the Notts Admins via their profile or by direct email: notts.labcaches@gmail.com
Information on how to play Adventure Labs can be found at: Adventure Labs FAQ
