The public grill is a staple at public parks, beaches and forest preserves. They're not usually much to look at, but they're sturdy and simple, albeit sometimes a little rusty. We've always shied away from public grills, preferring instead to bring our own, but maybe our reluctance is unfounded.
The fire itself should kill any lingering bacteria, maybe with the help of a grill brush beforehand. Then again, our little travel grill is so handy, and cute.
