Well, that was interesting - I went out for a walk and every time I came to a street corner, randomly chose a direction (for example, on a three way corner checked the second digit of the second count on my watch 1-3 turned left, 4-6 kept straight ahead, 7-9 turned right, 0 waited and checked again). Not a true Random Walk since there was on "turn around and go back" option, but close enough. I figured when I'd been out long enough I'd just head back, but by then I was already headed in the right direction. So I figured I'd check each corner until a choice sent me the wrong way. When I got to within a block, I didn't really want to go up to the next street (which was kinda busy) so when I got straight ahead I turned a block before. However, I still did the check and lo and behold, it woulda sent me right back home. Not at all what I was expecting. :)

Interesting! I'm sure some mathematician could do something about it, but I'll just say "interesting hike!"
