Into the forest.

Even though you’d love to go into the city, you’re buck naked, and that would probably get you arrested. You turn around, and see that the door you just came out of is the only visible trace of a manmade complex existing here. A hill rises up behind it, and you immediately take off up it. The steel pistons in your legs propel you to sixty, seventy, eighty miles per hour.

You come sliding to a stop at the edge of a cavernous ravine, across it, some people are milling about. You could probably jump across, but that would definitely give you away, or you could try to fashion a bridge out of... something, thus keeping your cover intact.
