Ok, I know what wardriving is and I've done it a few times myself (just scanning, not hacking into network). So I have two questions:

1) Why do people wardrive? I mean if you were to wardrive in my neighborhood, all you would find is a bunch of families. Nothing really that special.

2) If someone is wardriving on my network, and they are trying to break my encryption with prgms like AirSnort, is there any way I can find out/stop them?
