Hi Erick, I worked out the LP overlay this morning, how cool is that.
My place is right on the edge of blue to grey but our place down the coast is right in the middle of a black area. No wonder my C8 performs so well down there.
I've been using Wiki Sky for a while - GoogleSky seems to be of a similar concept except that Wiki Sky is browser based, you don't have to install any new program - it DOES pull a lot of data though so it's broadband only.
