The only way to prevent midair collisions....
I will give you another way to make a huge start..... I was coming out of your neck of the woods, (Darrington, WA) yesterday and went nose to nose with an R-44. I tried calling on 123.02 and 123.90 (the CTAF for Darrington), with no luck. He was flying along the powerlines on the left side---wrong. I am guessing you are working in the industry up there...maybe you could start to spread the word up there to the flight schools in Washington......
