Well .. on another tack ...
If it's possible, just rent a Bosch electric jackhammer and take the top off
the tower base concrete...the chisel will cut the Rohn 25, too ... ... down
a foot or two + ...
Problem is if the area would ever happen to get rototilled, could get
interesting. If so, go low! Fill in the hole, replace the topsoil,
sprinkle a few grass seeds, and VOILA!
