RH% in Midland right now is 13%. The shop's probably a little higher 
than that, but not a lot.

Steve,
It's better to drill them dry than humid. Depending on how the block has 
been stored, it's at around 6% MC. This block will certainly react to 
humidity changes, and get tighter as the humidity rises, and looser as 
it falls. Go for it.
