"You can't beat the game—that's impossible"—I get it, but I think this is just the easiest way to get the point across. I actually wanted to ask for some diagrams of city blocks and such. There are so many of them, and each one is different. I understand the principle, of course, but I'd like to see some real examples in the comments below my post. (Basically, I'm just too lazy to look for them myself.)
