Heathrow Spotting?
I know this probably isn't the right place.. but I'm going to Heathrow in a little bit to pick up some family, I'm arriving a few hours before they land to watch planes go in and out.. I've looked online at plane spotting areas and I'm just wondering what is the best one for free parking but with good views? I won't be taking professional photos so if there's fences in the way etc it doesn't matter....
Thanks
