Somebody told me that a local cacher is about to turn 60 & although when preparing Bullseye ten years ago we said "this is the last time", =Andy_R, 2ndEast & I could simply not let this occasion pass unnoticed, so IceColdUK, once again this cache is all about you!
Over the years we have enjoyed plenty of Geocaching adventures with you, both here & abroad, tackling long series’, attending Mega events, travelling silly distances in a day to hit an arbitrary target & enjoyed tree climbs / roping down into caves - which you always throw yourself into, despite a touch of vertigo.
Lately you have claimed to be out of touch with puzzles, but are a prolific, fast solver & have a large back catalogue of (pretty tricky!) puzzles. There are definitely some goodies in there, covering many different themes.
Anyway, back to basics, this is a puzzle cache so you will not find it at the above coordinates. Instead, take a look at the page & identify 8 numbers which you should label A-H in order, then use those with the following formula. Pop that into the checker for further instruction. What you waiting for?!
N51 ((C*D*F*G)-((A*C*F)+B+H))/1000 W000 ((A*C*D*G)-(A+B+E+F+G+H))/1000
