I have never done a survey, but I can say that all of the stars of the
Little Dipper are visible from my place a mile south of ASU. The two
Handle stars beside Polaris are mag. 4.3 and 4.2. By far, the most
difficult is Eta UMi, at 5.0, but it's always there. This is not to say my
sky is good. When it's overhead, the star cloud in Cygnus between Sadr and
Albireo is only faintly visible.

better late at night.
It certainly gets better after midnight. At the very least, many athletic
feild and billboard lights go off. A small number of people even turn off
their porch lights.
