I don't yet own an SQL meter, and I should, and I will, but I know many of you own them because I often read reports from Cherry Road, etc. But for a basis of comparison, have any of you taken readings in, say, urban Glendale, Scottsdale, Phoenix, etc. Likewise, have any of you taken readings in what are considered the "better" areas, such as Fountain Hills, Desert Hills, Carefree, New River, or North Peoria. Any numbers from any places as described would be of help to me in preparing for an upcoming presentation on light pollution. Thanks!
