Not wishing to argue but
1) I could use a 4 stroke.
2) Driving/Flying or going by train to the resort are not exactly polution free
3) Bridges/weirs/dams/roads which provide access
to the mountains ( esp in this country )
mess up the environment as well.
3) There may be a snowmobile course somewhere
which would not disturb skiers ( a very sensitive lot apparently )
No need to answer I am signing off
