There's definitely a story behind the name for this cache. It began over 40 years ago when I rode my motorcycle over the mountains for a short camping/fishing trip. I made camp here, and that evening as I prepared to cook my trout dinner, I realized I had no butter or oil to fry the fish in. It seemed most everything was fried back then, and being a neophyte cook I didn't know I had other options.
Applying my teenage mind to the problem, I thought "Hmmm, peanut butter...". Hey, don't laugh; I was serious! Let me say this: peanut butter burns easily on a fry pan over an open fire and it imparts a wretched taste to trout. Note to self: Cashew Chicken, "yum"; Peanut Butter Trout, "yuk!"
Although the trout made the supreme sacrifice for me, I was not willing to do the same for them. I settled for a PBJ sandwich that night.
