[TowerTalk] Fall Zone

[Richard Solomon]

A tower may be a thing of beauty in
your eyes, but look at it from the
perspective of the guy next door.

I was invited to a co-workers house
for a 4th of July BBQ. This was a
typical suburb setting, houses on a
10K Sq Ft lot. Two doors down the
street were two towers, 100' and 80'.
They were loaded with antennas. Just
imagine yourself in this guys shoes,
looking up at that mass of steel and
Aluminum towering over everything.

And, yes, both towers had proper permits.

Being Law, common sense or common
decency, the rule of falling on your
property is, IMHO, a good rule and
should be followed.
