Ya know, I have learned quite a bit on this little bulletin board. I remember this subject coming up before............months ago. I see the "regional" ignorance of some of us who don't go past our front doors to appreciate the specific problems (materials, etc) of others who live in areas other than ours. Thanks to this little item, I now have to go on-line, or worse yet, the library, and find out what in the hell this "artilliary fungus" is. Believe you me, I will discuss this issue with my friends, mostly builders, painters, carpenters, and see just how much "they" really know.
