Real easy! Unfortunately we didn't have a battery on us, so we'll have to go back later today to sign it.
After the last one we found at the mouth, we knew what we were looking for, too easy! Unfortunately we didn't have a battery on us, so we'll have to go back later today to sign it.
My brother and I found this today. Nicely hidden, but it didn't take us too long. The clue was a little tricky tho.
Found it but was annoyed to find our coordinates didnt work. Tried again and still no luck! Next time will have to come armed with something more than a mobile. But otherwise the puzzle to get at it is amazing!! Just need the right code
