It’s Pittsburgh Vintage Grand Prix week with events going on through July 25. Tonight is the Invitational Car Show on Walnut Street. Here you’ll see a really cool collection of hot and historic cars. Walnut Street will be closed, so you can get a good gander as you stroll past these vintage automobiles. See our 2019 photo story on the event. While there, enjoy dinner in one of the neighborhood’s fine establishments. 5 – 9 p.m. Shadyside.
