I picked up this TB from Dunnet Head as I knew we were off to John O'Groats next. Unfortunately when we got there the weather was so bad that I couldn't tempt anyone to the nearest cache and I totally forgot to take a photo of the TB at John O'Groats. I bought a bookmark when I was there, so the best I can do is post a photo of it with the TB to prove it went there!
I hope this is enough proof and the TB can win the race, otherwise I'm very sorry as it's come back to Sussex with me and I won't be back in the Highlands until July!
