Probably not free.

Funny one, not on the subject here, but sort of related. I'm in the airport in Manchester, NH stuck waiting for a delayed flight. I fire up the Laptop and am confronted with the pay to play on the airport wireless. Well, it isn't worth it to me that day so I sort say OK and don't bother, other things to do on the computer. While staring into space I see the famous orange female RJ connector on a pole (holding up the roof- between gate seating areas). Being a little reckless (foolish many could fairly say) I yank a wire out of my back pack and look to see if the post is hot. Bingo free Internet access and best of all a power outlet as well a few inches away so got to save battery for the flight. So much for homeland security, I didn't try to snoop the network there, trying to be a good boy, but sure did seem open if I could get an IP from whatever DHCP server was going and get to the Internet. This has been several weeks and no visit from the FBI so I assume no one actually cared. But I still wonder if someone of a less then 'honest' bent had jacked into the same port?

fundamentalism, fundamentally wrong.

Wow. In the two airports I frequent most, Toronto & Halifax NS, I can rarely even find a power outlet!

Maybe they use wireless power?
