This checkin to GC5H8YX Boundary Brook: The Mouth of the Brook reflects a geocaching.com log entry. See more of Dan's cache logs.
So pleased to see that this – an extension to my favourite series within the Oxford ring road – exists. Looking forward to an expedition to it as soon as I can manage it. I suspect that my friend lizrosemccarthy might beat me there though: she might even get FTF, as this cache is almost on her doorstep!
