I will make a comment about "free" WiFi....
[rant]Just because it's there doesn't mean you should use it.
Now, for people who freely advertise or state clearly that they will allow you to do it, fine. But just because some poor schmuck doesn't know how to lock down his WAP doesn't give anyone the right to use their bandwidth, no matter how little it is. In my opinion (and yes, it is my opinion, you are free to hold others), this would be as if you left your front door unlocked, and someone came in a watched a little TV while you were gone. No, they may not have taken anything, but still it was your property that was violated. Some would say that bandwidth belongs to anyone who can get it, but that guy is paying for it, and unless you are willing to pony up some cash to the guy or he is OK with letting you use it, it's not yours for the taking.

And now, back to your regularly scheduled program......
