Hi Dan, I just checked and Tonopah is a 90 mile RT for me. At close to $4 a gal and 15mpg it would be too expensive for me. It's too bad the people cannot just use a cheap spectroscope. You d not need to know much about hte spectrum. Just look at various lights of know type and compare to the light in question.

I'll leave out the more "destructive" solutions for those offensive bulbs, e.g., 22 caliber sky darkeners. :) I thank you all for your input. But I still need a volunteer to go out there and do a positive ID on those lights, which I strongly suspect are mercury vapor. Violation of ARS 49-7, if true, would open several additional options for a remedy. Ann says she'll provide soda and cookies for any volunteer. I'll wait for responses through this weekend, but need to wrap this up next week. If anybody can do this, email me off-list and I'll provide contact info and a location map. Many thanks. -Dan Heim -- See message header for info on list archives or unsubscribing, and please send personal replies to the author, not the list. -- See message header for info on list archives or unsubscribing, and please send personal replies to the author, not the list.
