I started the Johnny Appleseed series about three months ago as I watched my caching karma droop over the years, and felt the need to give back, and explore the local trails in a different perspective. Since those 50 caches were placed, my karma has doubled from 0.35 to over 0.70, so I'm starting round two, sprinkling caches along the trails just a bit farther from home.
This cache is on the High Meadow Trail in Rancho San Antonio, one of the busiest parks in Silicon Valley. This trail can be Muggle Central, so adding 0.5 to the difficulty. GPSr should lead you right to it, but the hint should keep you from getting too bogged down in your search. You should be able to search with your feet, just pretend you're on a mysterious phone call. 
Please replace as found.
Congratulations to catomcat for another Rancho JAS FTF!
Good luck, enjoy the trail, and remember it is good to give back!
