Close encounter with a Blackhawk today

This afternoon while out flying I had a close encounter with a Blackhawk
8 miles from the White House.
I had another close encounter with a Huey, several news copters, a
police copter, a 747, several Traffic Cessna's.
We just waved as we passed. ;-)
Ok now that I have your attention..... I fly one of those aircraft as
well. I fly Traffic survey over the skies of Washington DC.
Always one our toes below 1300 is too low and above 1500 puts us in the
Class B most of the time. Always talking to someone.
