Whenever you come, you're sure to run into some activity or other -- a jazz festival, a tea garden or tavern gambol, a quilt exhibit, a wine tasting, or an organ recital. But note that many of Alexandria's main attractions are closed on Monday.

Save with a Discounted Attraction Pass -- Alexandria's Ramsay House Visitor Center usually sells money-saving discounted attraction passes to some of the top sights. A combination ticket to Gadsby's Tavern, Stabler-Leadbeater Apothecary Museum, Lee-Fendall House, and Carlyle House Historic Park recently cost $12 for adults, $8 for children 11 to 17. The passes change from year to year, but it will pay to ask the center what's being offered.

A slave compound occupied most of this city block. The museum is operated by the Northern Virginia Urban League, which shares the building. Open Monday through Friday 9am to 5pm.

Union St. (tel. 703/838-4399;, on the third floor of the Torpedo Factory Art center. It shares space with a working laboratory. Admission is free, and it's open Tuesday to Friday 10am to 3pm, Saturday 10am to 5pm, and Sunday 1 to 5pm.

If you've ever had a clever idea for an invention you thought would revolutionize the world (and make you rich), walk into the U.S. Patent & Trademark Office Museum, in the USPTO's Madison Building, 600 Dulany St. (tel. 703/968-4332;, which uses high-tech displays to explain how ideas for famous products came into being.
