I would be bewildered. I would check to make sure the person is all there mentally -- in that they might need the money more than me. If I still got the money, I guess I'd put it in the bank -- unless I met someone along the way who looked like they needed it more and then I might give them some or all of it. (I found $700+ on the sidewalk one time -- someone had dropped their entire cashed paycheck.

What scene (landscape, city, etc -- doesn't have to be famous, maybe like a river or valley, etc) in the world are you wishing that you could gaze upon right now?
