Re: (ET) Final snow-blow, this time with numbers.

-- oops - lost my reply in my first try --  here it is ---

I became the neighborhood 'Mr Plow' this year as my neighbor is getting 
a bit old for the cold weather stuff. So I've been running his diesel 
tractor this past week. My ET could not have handled everything I have 
to plow this time, but now my clothes smell like diesel. I miss my ET.

But I wrote mostly since I had the same thoughts about the snow cab 
today - now I understand - it was a bit tough out there in blizzard 
conditions. I basically was dressed for snowboarding - down to the 
goggles, so I stayed reasonably warm and dry, but it wore me out being 
out in the wind.

Looking forward to no snow, no wind, no clouds!
