[TowerTalk] blocking a crankup

[Jim Jarvis]

Doesn't matter a whole lot what you use to block the
sections...

BUT MAKE DAMNED SURE YOU BLOCK ...AAAALLLLLLLL..... 
THE SECTIONS!   

2x4's are sufficient for smaller towers, up to 50-60',
but do not fail to block the upper section before you
get your toes and fingers in there.  even a 1" slippage
could pin you in a very awkward position.

Else, your cw may be choppy...and your baserunning 
may result in you being called "toeless Joe"  

Also, I would strongly recommend a buddy system, not
solo climbing.
