Quick Park 'n Grab on the way to catching the train. You can probably park right next to the cache (if the spot is open).
Please do not reveal anything concerning the cache container. Logs that do will self-destruct in a matter of minutes.
On second thought, you may want to wait to look for this one when you return to your car at the end of the day. Don't forget to bring a pen or pencil, or even a sharpie.
Congrats to FTF - CalypsoAria
