This is one of a series of caches that celebrate films made by writer/director Quentin Tarantino, as well as taking the cacher to some out of the way places and experiences.
Reservoir Dogs was made in 1992 and features a scene that sticks with most viewers, the song "Stuck in the middle with you" is never quite the same after this movie.
While not exactly a picnic spot, this reservoir seems a fitting spot for a cache honouring such a riveting and sometimes disturbing movie.
