Followed the clues but never found cement so could not locate the box. Had quite a trek through the shrubby area.

I am familiar with this area as my granddaughters used to go to the charter school nearby. The directions are very good and the distances accurate (as measured by my GPS). Easily found what looked like the intended spot, but I found no letterbox anywhere around it. The rocks looked like they had been deliberately moved around and disturbed by someone. I spent another half an hour wandering about in that maze of trails looking for an alternate site and any other place that might of been the hiding spot, but couldn't find any. Turned over lots of rocks in my hunt, but had to walk away without a find.
