Yep, that's right, it's a large. I was hiking in this park last October and saw this spot that deserved a decent size cache. I finally got around and returned here with an even bigger one than I was initially planning on. From the parking lot take the Umbrella Tree Trail to the west. I recommend exiting the trail near a metal gate. This is one of the few colors remaining for those of us doing the Crayola Color Challenge. Big props to Loqrotimus for scoring this awesome container and offering it up to me(He may not appreciate the decor, though). There is lots of swag and trackables inside so be prepared to trade. As for the title, I couldn't think of much except for what would "The little engine who could" say if it saw this cache.
Congratulations to Beeezzzz on the FTF!
