WiFi Repeaters Working Over Half Mile

I did it. The ultimate test of my new Netgear WNDR3700 Routers setup as repeaters. One as the base station plugged into a router with internet acess. The other working in repeater mode picking up the base station a half mile away and then a DLink Router plugged into the repeater which serves the internet to all my wireless and wired computers. This is great! Maybe now I won't have to run hundreds of feet of wire across parking lot or through the woods to get to the internet for our broadcast.
