If you’re on Facebook, you must add “Preserving St. Louis” as one of your friends. “St. Louis City Talk” is also fun — but “Preserving St. Louis” is just fantastic if you want to trip down memory lane and recall the places, sights, sounds (even tastes!) of St. Louis. “Preserving St. Louis” gives a brief history of an iconic business, person, or other item of interest — and then tells what is happening with that business or person today. Great stuff!
