Metric, Imperial, Archaic, or Arbitrary, it's almost indescribably unpleasant.

I am in Western MA, in the Connecticut River Valley, where the summer air sits stagnant on top of you like a sweaty hippopotamus.

My bedroom is on the third floor, along with 2050 watts of HID lighting. The ballasts throw so much heat that even with an a/c running at full blast, I could not get temps below 95.
I slept on the damn sofa last night.
It was either that, or the hammock in the back yard.
If it weren't for the pack of coyotes that have been poking around my 'hood, the hammock would be preferable.
