[TowerTalk] trees and verticals

[kr2q at optimum.net]

Hi Eddy,I have no clue.  My educational background is in Biology (ugrad) and Veterinary Medicine (doctoral).  I currently (and for the past 15 years) am working in healthcare (hospital administration).  I also have a degree in Hospital Administration.I have been contesting for over 40 years.  I hold many current contest records.  I have helped build some of the largest ham antennas in the world (when I operated at a M/M for 10 years).  I am an empirical type of guy.  I report what I observe.
