I usually miss qualifying on Friday as well. Then it snowballs throughout the weekend trying to fit everything in. In the end I just give up and watch highlights after the race because I haven't invested any time yet to want to watch the race.
It's gone from watching an hour on sat and ~2 hours on Sunday. To 1 hour Friday, few hours sat and a couple hours Sunday. I just don't have that much free time to give up.
'Natural' gas is just gas. It's not a clean emission free fuel. It's better than coal but by no means a clean fuel.
