I have something of the same problem (though proabably a lot
less) here in Central New York, where the glow from Cortland
(c. 15 mi. away) intrudes upon my southern sky. To the
north, sadly, things are even worse because of the much
larger dome from Syracuse. 
OTOH, instead of moving the cosmos up, we could work to get
the "light domes" lowered. Here's a start:
