Time Out says
Nosh on gratis burgers and hot dogs or sip fresh-squeezed lemonade at this outdoor celebration, where a 100-pound pig will be sizzling on the spit. Claim a seat at one of the picnic tables in the closed-off street, or grab a pint of Blue Moon or Guinness ($5–$6) inside the Iron Horse. Donate a few dollars to snag a plate loaded with slices of roasted pork in a burger bun, with macaroni and potato salad sides. All donations will go to the Wounded Warrior Project, which helps raise awareness about and provide services to injured service members.
