Last night at 2:30 am 7/13/2015 in Berkeley CA, I was suddenly wide awake for no apparent reason with a slight burning in my lungs. I checked an app to see if there had been a shift in the wind. Possibly. I was close to the freeway and the breeze may have been carrying fumes from the endless stream of cars.
Or perhaps a secret can of military “no sleep gas” was dropped upwind. Whatever the case, it took a few hours before I could sleep again. No big noises, no earthquakes, nothing else seemed to trigger it.
In the process of looking at wind maps, I found this one I though you might enjoy.
An invisible, ancient source of energy surrounds us—energy that powered the first explorations of the world, and that may be a key to the future. This map shows you the delicate tracery of wind flowing over the US.
