i really wouldn't encourage people not to worry about it. i have lost a lot of good bud to a little bit of rain. i now go out of my way to be overly cautious. it has been nothing but beneficial.If you shake your plants to rid them of excess moisture, they are usually ok unless you already have a mold problem.
I'm in the 209, and have never covered a plant or lost buds to mold, because of rain.
