It's a weekend tradition for hardcore pickers and casual browsers alike, but there's no need to wait for Saturday or Sunday to peruse the packed aisles of antiques, collectibles and vintage finds that line the funky little strip of Hildebrand Avenue between San Pedro and Beacon. While certain spots come and go, mainstays Antiques on Hildebrand (501 and 521 W. Hildebrand Ave.) and Lasting Impressions Antiques (600 W. Hildebrand Ave.) offer veritable mazes that can turn shopping for retro furniture, light fixtures, period decor and tchotchkes galore into a full-fledged treasure hunt.
