SRS;
thanks for that Chief Seattle info; between the websites kat mentioned and yours I have learned a lot about him! I would love to knwo what he really said...

My high school (which was built in 1979 for several million dollars and considered a state of the art building at the time) was indeed built near a toxic waste site. nothing was said about this at the time. I myself wondered why it was built in "the middle of nowhere" a vast tract of uninhabited land in a suburban area...I am not sure what has been done to clean up the problem but the high rates of cancer did make national news headlines...I will try to find an article.

Gurney: those light on tall structures cause some species of migrating birds to die in huge numbers. They crash into them because they're too bright and the birds get disoriented. Presumably lower-intensity of brightness would still serve to warn aircraft and prevent such high bird mortality.
