Hidden Falls Puzzle 2015 Mystery Cache

Another cache for this great hiking area known as Hidden Falls. Well marked dirt trails and typical hazzards for the area. Snakes, Ticks, Stickers and PO.

 It's been a while since I did an EVIL puzzle cache in the area .... well, not too evil but it is a puzzle. CACHE IS NOT AT POSTED COORDINATES!!!!

To find the actual cache you need to solve this little puzzle.

PUZZLE:

3+5-3+3-8+7-1-5+1-1-0-0+3+2+3

Simple right?????

Cache is a large container with the normal goodies. It's hid just off the trail in a obvious area.  

Please be aware of your surroundings at the final location. Make your presence known to avoid a meeting with Mr. Rattles.

You can validate your puzzle solution with certitude.
