DaveI should mention that I don't live in a swamp, almost a desert, near Spokane Wa, where the average humidity lately has been in the 20's or 30's.
As a side note, be sure the containter of dessicant is well sparated from the cards because it will end up in its own puddle of water if left alone.
I like the idea of a box with red/blue patch as an indicator. I'll look for that next time.
