Geocache Description:


Yup, you've seen them around. Near schools, public bike racks and bus stops. Abandoned combination locks. Sometimes they stand out like the forlorn and useless reminders of a job failed or a combination forgotten. Other times you have to wonder just who would elect to leave a lock there, of all places?

To find this cache, visit the first Reference Point. There you will find a lock and a method to convert numbers. Convert the original 3-digit decimal seconds (N1 and W1) from your listed cords to generate 2 new numbers. We'll call them CN1 and CW1 (C=converted). To find WP2 (N2 and W2), use the following formulae: CN1=CN2 and CN1-CW1+56=W2

At WP2 you'll find another lock. Use it to determine the final cords (N3 and W3) using these formulae: W2-(CN1-CW1)=CN3 and CW2-CW1=CW3.

To unlock the final cache, apply the following formula: original CW2+CW3=Tadah!

You are also encouraged to complete an additional logging request by posting a picture of other abandoned locks with their brand name (if you can make it out) and their precise location via a Waypoint log. Any kind of abandoned lock will do.

UPDATE 7.14.09 Numbers updated. Some adjustment was necessary

UPDATE 9.1.09: Challenges removed from this series. I'd like more cachers to attempt these caches and the requirement was too constrictive. Please attempt the alternate logging request outlines above.

UPDATE 5.14.10: Complete overhaul due to missing locks. Should be a little easier now, from a distance standpoint. Also, you do not need to go inside the fence. If you're solves seem to take you there just ignore them and stay on the outside.

UPDATE 7.20.10:
Revised combination to fit the replaced final.

UPDATE 8.10.10:
Slight adjustment to lock combo.
