Any flyfishermen on here?

Read in the local paper this evening that Missouri was outlawing "Porous" type waders. They say they are responsible for the transfering of some type of algea that grows slime on the rocks at the bottom of streams. Does your state have a law like this in place? I guess i'll contact the Conservation dept to get the scoop on the correct type of wader that is allowed. I've been useing the neoprene sponge type and they seem to be porous. I wonder what will be next.
