An actual letterbox in Orange County!!
Recently several of my caches have been muggled by pigs. To avoid the embarassment of having my caches being found by thumbless Sus' I have hidden this one as a letterbox. As such, you will be given no coordinates just some directions and two pictures.
Take a hike on the red trail. At some point you will see the following bridge, 
At this point look for the following rotten stump northeast-ish from the bridge for 108 steps. 
Inside this rotten stump you will find an ammo can. There are several books, dvd's and a stamp. DO NOT TAKE THE STAMP!
