This cache is the bonus final for New Bedford's Love the Ave Adventure Lab series. To obtain the coordinates, you must complete the adventure lab series, and upon completion you will recieve the coordinates. The adventure lab series is available using this link.
The final cache is a magnetic keyholder that should be winter-friendly. There should be street parking available nearby, but it will require a short walk no matter where you park.. A Certitude link is included below for confirmation of coordinates, and a hide hint will be provided there as well.
Hope you enjoy the series!
