Welcome to the 'An historic and poetic wander round Chiltern Adventure Lab' Bonus Cache!
The adventure lab you will need to complete https://adventurelab.page.link/EeCC
The coordinates are false - you will not find a cache at the published coordinates, don't go there as you will get wet.
To find this cache you need to workout five rhyming words, one at each stop on the adventure lab. You will only discover these on the completion of each step of the adventure lab so please check the completion page. You will need to put these in the checker and if all works to plan then you will be given some coordinates. The words need to be put in, in the correct order with no spaces - for example trueshoeblue etc
Once you have the coordinates you will need to visit a location that is outdoors but not community land. This cache is placed with the landowners permission and they do know all about geocaching and do expect visitors. They have asked for two requests, please do not drive onto the property but walking is encouraged and don't visit at ridiculous o'clock.
They cache guardian is a tall gentleman, or lady that likes to keep an eye on visitors
