Well our first attempt at lucky 13 wasn't very lucky. We placed it literally right on top of a final for a puzzle cache. Even worse, it was one we had already found 
so we should have known. hopefully this will be a little better since it appears to be away from everything that i can see.

Lucky #13, it can get busy on this road so make sure you use the pull in for parking.
Field puzzle trail, Some will be harder than others.
I would suggest not trying these on blowing cold or rainy days as ttey are all tethered in place and being field puzzles they may be challenging and take time. Please do not attempt to untether them so you can work on them in your car. They need to stay in place so animals, rain, and wind cannot take them away.
have fun, others may be easier but there will be some tough ones like this one!
