This is a key lock container, and should be a quick find for you. You can park up on Water Way and go down the sidewalk to the cache. Happy hunting!
Congrats to Lostindenver for the FTF, along with Rohatx, Jinxer05, Geoninja2, Windatmyback, and 2lablovers, for the FTF! It was a cool impromptu meet-up!
