Narrative:

I was flying in an area of very heavy helicopter traffic. I have flown in this area regularly for the past 20 yrs. I had just departed a helicopter and was in cruise flight when I saw a shadow pass off the left side of the helicopter and then a helicopter pull away to the left. Both the other pilot and I made the normal position report calls for our operating area but did not hear each other. (Perhaps we cut the other out). I recommend to all pilots, look for other traffic in the most unlikely places, I mean straight down, up and constantly clear your blind spots. Even do clearing turns to be able to check as much of the sky around you as you possibly can.
