Friends are like antique cars: If you collect the good ones and keep them for years, they'll only increase in value -- not to mention they'll drive you around wherever you want. Grab one of your nearest and dearest and check out today's deal for the Marshall Steam Museum at Auburn Heights: Pay $17 and get a family admission for two adults and two children ages 2 to 12 to Steamin' Days (a $34 value), or pay $10 for two adult tickets for ages 13 and up (a $20 value). Operated by the Friends of Auburn Heights Preserve, this museum boasts the world's largest operating collection of Stanley steam cars. From June to November, stop by during the first Sunday of each month from 12:30 to 4:30 pm for old-fashioned fun at Steamin' Days. Experience a demonstration of one of the 15 working antique cars (some more than 100 years old), enjoy fresh-steamed popcorn, check out the museum full of kids' activities and exhibits -- and don't forget the gift shop. No need to wheel and deal for a fun family outing -- save 50% without even breaking a steam -- er, sweat.
