[TowerTalk] Fwd: Aluminum towers -- can you really "walk one up"?

[Roger (K8RI) on TT]

Easily,

I've walked a 40'  25G steel tower up by my self when in my mid 60'  and 
at 5' 7", I weighed less than 165#.  The one arm/hand rests momentarily 
while the other holds, then both hold, giving both a bit of a rest 
holding half the weight each.  the part after the maximum weight gets 
lighter rapidly.

However it works, the 40 footer was a relatively easy lift while it took 
a "bunch" to do the 50 footer.
