I've spent 5 days in London on the occasion of the Mega event.
Sadly I had lost my notes of all the TBs and geocoins that I discovered over the those days, only to find the remains in the wash..... There was no way to separate or remember which ones I saw on Friday evening, at the main event on Saturday, at the Cito on Sunday, on someone's t-shirt or in someone's hands. Therefore I have reluctantly decided to log the few I could still read with the date of Saturday 28th.
If, as the TB/Coin owner, you are not happy with this, feel free to contact me or to delete the entry.
