Nothing builds ties like pulling potatoes with your neighbors. That’s exactly what a few North Carolina farmers discovered in 2008, when they started throwing on-farm work parties to help each other complete projects. Since then, so-called “crop mobs” have caught on throughout the country. And it’s not just farmers getting their hands dirty: you can too. Volunteers help spread mulch, build fences, pull weeds and harvest crops. Though helpers shouldn’t expect anything in return, the bonds made are real. Get more information at cropmob.org.
