I was shopping at a Wal-Mart on December 17, 2004, when I noticed
outside a helicopter flying just over the tops of the parked vehicles
in front of the store. It was flying towards me, about 20 feet above
the ground and climbing. I got a photograph of it when it was about 50
to 70 feet in the air. It quickly flew up past me and over the top of
the building.

I realize that helicopters have a lot of flight freedom, but it is
still shocking to see one flying directly towards oneself like this.

Coincidentally, an assistant manager at that store told me last week
that I was not allowed to bring my camera inside the store. He cited
security risk, and made a vague reference to the cameras they sell in
the Electronics Department. So, it may be difficult to get photos like
the one I took, at least from that store.

Helos are used to police major power lines in my area. My guess is
they are less than 50 feet above the lines. Everytime I see them fly
by I just give thanks that I don't have that job.
