Ken,
Are you aware of PAS President Rod Sutter's sky quality site? Might be
some of what you're looking for there. See:

FYI, DFAC did an observing event for a convention last night. Skies were
clear. No Moon. We were at Baseline & 27th Ave, and for us (a north
Valley club) it was weird to have the Phoenix light dome north of us.
Had a great view of Sagittarius, but the Little Dipper (which was on the
meridian), was totally invisible. Took a reading with my SQM-L and got 18.4.
