OK, let's clarify something about dust. The FACT is that if you breath ANYTHING (dust, mold, spores, smoke, exhaust, micro pariticles of anything) for an extended period of time (generally thought of as years) there will be PERMANENT damage to your lungs.
Another FACT: there is NO regeneration of lung tissue, not even kids. The lung tissue does not have the ability to regenerate.
There maybe very little medical grade research about "playa" dust and respiratory problems, however, don't think it doesn't hurt. The LA DWP has had to (under court mandate) do something to decrease the dust on Owen's dry lake bed. They are planting salt grass and refilling parts of the lake bed to decrease the dust that affects the citizens of the owen's valley due to resp. problems.
I don't believe that a week or two of heavy dust for the average person will have any long lasting problems. The real problem is long term inhalation, think of smoking cigaretts. It's not the week or two you smoked, not even the year or two that causes COPD/ASTHMA, it's the constant barrage that makes for problems with your lungs.
So let's stop thinking that this playa is forever gonna fuck up your kids, or your lungs for that matter. There MAY be some people that are genetically more sensiteve to playa dust than others, but there's currently no way to test that theory. Be smart, use a mask.
Let's also stop thinking that the "environment" is not safe for children. This human species has survived millions of years, in much worse conditions than these we encounter, and yet here we are, more people on earth than ever!
So, lets boil this down to what it really is: People's morals and values
I'm not gonna say what I would do if I had kids, cause I don't have any, thus there's NO way to say what I would do. I do believe that it's eye opening for children, and they'll see much more disturbing behavior at school than they will at BRC (think of all the bathroom pranks at school, the school yard fights, the shit they see on your computer/internet when you are sleeping/not watching).
If you bring your kids, and you take care of them, I don't have to. If you leave your kids at home, someone else takes care of them, so I don't have to, cool!
There's no right or wrong answer, just a lot of very emotional people, even more emotional when it comes to you telling other people how to raise their kids.
It is nice that we can be adults and discuss the realitys and beliefs on such a tuchy subject.
Most of all, have a FUN burn, it's what you have waited all year for

Chillax, dude.
