screw in stakes - These are great but need an impact drill to screw em in. Other screw in stakes are good too. Attach your guy lines to these then use 12" heavy duty stakes for the legs. I filled water bags up at the festival with water - bring a wagon they're heavy - to attach to the legs for extra weight.
