I reported a *21.2* at Farnsworth Ranch.  The previous weekend I was on Mount 
Lemmon, where the SQM gave 20.8 at about the same time of night.

The 0.4 magnitudes of additional brightness at Mount Lemmon is compensated by 
the 7000 feet of additional elevation.  Overhead, the Milky Way detail was 
better at Farnsworth, but as you worked you way to lower altitudes, Mount 
Lemmon was superior.
