<snip> you may consider drilling a 1/8 inch hole aprox 1/2 inch above earth
level.
Bad idea. While it is true that water will condense inside the tower,
the right way handle it is to install the tower so that water can drain out
the bottom by extending the pipe or base section far enough down into porous
material. Others have mentioned this and it is very important. I've seen
many towers where this wasn't done and every one of them has ice splits in
the legs.
Drilling any extra holes compromises the strength of the tower,
especially near the base where the bending moment is highest, at least for a
free standing tower.
