Come to Michigan.  We not only get lake effect from SW all the way 
around to SE. but the acid rain from the industry all the way around the 
South end of Lake Michigan.  I couldn't open or close the N man door on 
the garage fot abour 4 months due to ths concrete apron and floor heaving.

The S man door on the shop is about an inch and a half above the apron.  
By the ebd of December I could only open it 90 degrees before the corner 
of the door fit the concrete,  At he end it reached the point that I 
could just squeeze in sideways  between the door and frame.


Our roads are covered with a mix of sand and salt, but most of the time 
the salt freezes too,so they go to Calcium chloride which I think is 
good for another 10 degrees.  So it slings the salt filled slush up to 
thoroughly coat the bottom and keep the salt there till spring.  You can 
wash it off, but it's usually coated thoroughly by the time you get home.

Chicago's acid rain (clear up here) makes a set of Aluminum screens good 
for a season or two.  With the sun and chemicals, nylon screens last 
about the same.

You really need a winter and a Summer car up here!

Dow "used to be" a problem.  In 61 with the wind out of the SE I could 
take off from the local airport and follow the cloud all the way to 
Traverse City where it was still only a couple miles wide.

Now you neither see it or smell it.  They have really made some strides 
in the environment. They blame Dow, but the are the ones who developed 
the ability to measure such small amounts to clean it up. No, I never 
worked for them.

Everybody has problems.  Conn is the government and taxes.
