This typically hidden micro cache is accessible from the sidewalk, but please do not park in the space adjacent to it unless you are qualified. Bring your own pen.
Here in Center City, there is always a muggle passing by; mind your stealth and have fun.
Be aware - the tall buildings and reflective surfaces that surround you may cause significant GPS bounce. This is a standard urban cache and the hint gives it away; the only way to make this easier is to place a sign at the hide location saying "the cache is here". That is assuming that your GPS didn't lead you astray.
Please be careful not to push the cache too high in its hiding space.
