If Google Earth is correct, that lat/long puts it on Firstfield Road in Gaithersburg, just SW of I-270 exit 11 (MD-124).
For those familiar with the area, it’s the apartment/housing/whatever area nestled in between the strip mall with Chevy’s and McDonald’s to one side, and the MVA on the other.
I’m guessing Chevy’s had something to do with it. Mexican food that early in the morning can do havoc to your digestion.
