Detroit's S BY ELLYCE FIELD I f your relatives hail from the East or West coasts or any other large metropolitan area in between, then I'm sure you're used to their comments. Just mention sightseeing on their next visit to metro Detroit. "Oh, we're just coming to spend time with 'you guys,' " they assure you. "Besides, what would we want to see in Detroit?" OK. So we're not New York City. Or San Francisco. Or Chicago. But hold on to your seats. Here's a sampling of hometown sites that are distinctly Motown. And trust me, they will impress the family.
