Snicker...mine are kept outdoors, under a roof 365 a year.

The only problem I have is the odd spider than makes it through the
screened in vents (I install screen in all openings that could lead to
bugs getting to a board. Shrug) Happens maybe once every 5-10 yrs

I am explictly thinking of the threat of vaporized/sprayed/whatever
metals taking up residence on a board....Never any of those in
the air near a welder, right?

But dampness is just as good a board killer.
