   The little bits that I have been able to track into my yard look like little blobs of sheer gauze (smaller than your little finger-nail).

   There was a prop-plane sound just before I noticed them, but I never could see the plane itself. I like planes, and generally watch them while smoking on my porch.

   I really would like to get other folks to witness this stuff while it's still there. It is easiest to spot if you use a building to block the direct sun, and then look at the edge of the halo (just the properties of light reflecting from the streamers).

Can you somehow get a sample? Put it in a ziplock bag and take it to a private lab for analysis. It's probably the ONLY way to get an HONEST idea/finding of what the crap IS.

The cottonwood trees are shedding.

And, for those of you in Rio Linda, yes, there is a cottonwood tree!

"...watch them while smoking on my porch...."

That could be your problem!

Hang in there Leroy. People can poke fun at you, but I want to know what's going on. DainBramage is watching something in the Fort Worth area.

take some of it (obviously without your hand touching it and please, with something covering your mouth just in case....)....take it to a private lab. They are the only folks who would tell the truth if it is bad. Then, make sure to report to us what it is....if serious, I will write an article about it....
