My 20 year-old son who's home from college is still on the hunt for a summer job. He doesn't drive so would ideally like something walkable in the Highland Park/East Liberty area, if possible. He's applied at a number of businesses but nothing's turned up yet. I know it's supposed to be a hot job market, so perhaps he's looking in the wrong place. Any leads or suggestions? It could be full- or part-time. Just something to earn some money and get some experience.
