Set for the 2018 Winter Geolympix with permission from the National Trust. If you intend to attempt the Letter/Box Challenge on Mega day you may want to leave this until then. Although Ashridge already had a 'U' Letterbox - Team Hippo's Up a Track, Up a Bank, Up a Tree (GC6JKWV) - it proved too small to take an ink pad and the stamp we wanted to use, hence this one was set closer to the centre of the site.

Please DO NOT remove the stamp or ink pad. Neither is a swap - They make this cache a LetterBox/Hybrid. Thank you!
