My name is Mark Ahlness, and I am a retired public school teacher, living in Seattle, Washington.
Most of my current online work (2016) is at the Seattle Nature Alliance.
Some pretty dated info here…
I first heard the word Acrovision in 1972, when I was attending UConn and working the night shift at a nearby state institution, caring for severely developmentally delayed men. I did not know what it meant. I still don’t.
