Hey hey, y'all. Here's a guest post from former GRS staff writer (and perennial reader favorite) Donna Freedman. This piece about becoming a frugalvore contains material that originally appeared at Donna's site, Surviving and Thriving. It's been modified for GRS. Enjoy! The “locavore” movement is based on the idea of eating only foods grown within a 100-mile radius of where you live.
