DEXCOM Platinum G4 : STICK IT WHERE?

I usually go with my lower abdomen when thinking about where to put my sensor each week, but also wanted to try out other areas that a few readers suggested awhile back, and wanted to give my stomach a break.  It's currently in the back area of my arm and so far it seems to work pretty good. It isn't as accurate as when it is on my stomach, but much much more comfortable.
