I'm sorry this TB has been off the radar for some time. It is now back on track and continuing the race.
I haven't been holding onto it this whole time, honest! I passed it to a few different newbie GCs to drop off but none of them could find the caches. (There have been a few tears from the younger GCs!). The Rugby Ball circled Yorkshire for a while until they finally gave up and returned it to me.
Thank you to everyone who tried to help, and to J who actually did! 😉
