Mind-bogglingly, Stupendously, Fantastically Amazing!
Okay, I'm going to geek out here, but bear with me because this is cool. I was talking with my ESRI tech support folks this morning (Thanks for all your help, Margaret - You rock!) about difficulties in calculating magnetic declination in our mapping software.
For those who don't know, I'm a GIS analyst. That's something like a cartographer and database manager at the same time. When people ask my profession, I generally say "Map Geek"; it saves time.
