Hells yes. We all need to be making a difference and its great to see the pros thinking about it too! I know its only Abma at the moment but it will catch on quick I am sure.
"wow - very cool. i was thinking the whole time i was reading it about...."what about his heli time, his sledding...etc." then i got to the part about the bio deisel fuels. way to go man."
I'm pretty sure they don't use his biodiesel for all the helis and dozens of international flights he takes every year. This maybe a step towards better but it's still far away from sustainability. If you want to be sustainable, quit skiing. Otherwise we can only slow it down. But props to Abma. I hope his initiative will start good discussions on the forum, as well.
