Maybe you are trying to start your family on a healthy track this 4th of July or maybe you just want something a bit more exotic than your average burger-and-dog bbq fare. Either way the folks at the Massachusetts-based Vegan Bus are coming to Philly to help make this Independence Day healthy and sustainable with a kid-friendly, vegan barbeque. If you prefer a more adult-centered event check out the Vegan Drinks 4th of July Extravaganzaa at New Harmony later in the evening.
