Not what it's cracked up to be Multi-Cache

This is a simple 2-stage multi-cache. You'll need to BYOP and a TOTT. Please take note of where/how you found the cache so you can replace it in the same spot. Thank you!

At the posted coordinates you will see a telephone pole. About chest high you will see some numbers in the format UDxxxxxx. Ignoring the leading zero, take the first 3 digits of that number and add them to the North portion of the Reference Point coords (not the posted coords). Then take the last 3 digits of that same number you just found and subtract them from the West portion of the Reference Point coords. That's it, now find the cache.

You can validate your puzzle solution with certitude. Congratulations to Sandy Bandy for FTF!
