According to this map (http://www.navcen.uscg.gov/images/Plots ... al_usa.jpg) DGPS coverage should be available at SparkFun in Bolder CO. Does anyone have any direct knowledge of signal availability? Often holes in coverage exist due to mountains, buildings, and other RF obstructions.

And yes, this is for AVC but not for this year.
