LOG ONLY: BYOP!!!
Hey Bunkson! Thanks for meeting me down here by the DMV. The beatles have once said, "Baby you can drive my car, and maybe I'll love you. Beep-Beep, Beep-Beep, Yeah!" Say, have you ever skateboarded Bunkson? You know, I never was any good at those things. When I was a chap, I always wished to be able to use one for locomotion. But alas, I found that bicycling was much easier. Anyway, head to the posted GZ and look around for an MMU#. The four-digit number will fill in the missing coordinates: 37°19._309'N, _7°3_._772'W.
