Dave,

I found that when I taught High School students the way you calculate
the temp was a little more difficult for my students. The formula
varies depending on whether you are converting from C to F or vise
versa. My students would forget when to add or subtract 32. With the
equation I use, they only have to remember to multiply by 9/5 when
going to F and 5/9 when going to C. I learned this formula when I was
taking HS Chemistry and found it helped me as well. Of course, I've
met other teachers in my career who told me the only way to to this
is the original formula, so perhaps I rebelled against conformity,
such as using a hammock rather than camping on the ground!

• Since the weather usually comes here from the west/ south & north Lake Effect snow doesn t happen here as much as it does to Northern Indiana, Michigan State

Since the weather usually comes here from the west/ south & north 'Lake Effect' snow doesn't happen here as much as it does to Northern Indiana, Michigan State and points East of Lake Michigan. This is because there aren't major bodies of water to the west to feed the snow. The most apparent and often 'Lake Effect' is during the summer as it is 'cooler by the lake' (up to 1mi inland) and in the winter it is warmer by the lake (~5-10 degrees).

still no overnight camping on the lakefront or in anywhere I know of in the metro area (25-35 mile radius from downtown) though. But there are lots of out of the way forested areas where you cant be seen.

weight 100grams (g) = ~3.5 ounces 1/2 an ounce short of a 1/4 pound (a nice sandwich)
Liquid 1 cup / 8oz = about 1/4 liter (L) 250milliliter (ml) actual
distance 1Km = .6 mi This also applies to MPH vs. KPH
10Km = 6 mi
100Km = 60 mi

Absolute Zero....
WISE DECISION I'm sure you would be missed !

While Chicago does have a breeze (most notable in the near north / downtown
area near the river), the moniker the "Windy City" comes from the long
winded politicians past and current.
