Well, what with all of these letterbox caches in Findon, there certainly are plenty of places to post some letters! So, I thought I'd give you all a chance to maybe rack up another 'Going' puzzle.
I love posting letters and the more I have, the better! I never get bored of it.
So anyway enough of this tittle tattle, time to work out the puzzle. Well, it's simple mathematics is it not? What could be easier? I'm sure I've no need to spell it out for you, you should know the score by now. Just like all of the 'Going' puzzles once you stumble upon the theme, it will all make perfect sense!
The cache can be found at.....
