I’ve lived in STL my entire life and seen lots of Cardinal championships and a Super Bowl winner (Stank Roenke can rot in hell for moving the Rams).
I can’t remember any felonious behavior at any of the celebrations.
STL gets a bad rap on crime. Stay away from about 5 square miles in north St. Louis and it is extremely safe and very friendly....a great place to raise a family.
FWIW, East St. Louis (of Vacation fame) is in Illinois.
I’ve always liked St. Louis. Toured the Cahokia Mounds site a couple years ago. But I remember getting lost driving through East St. Louis in 1972, on the way to visit a couple friends who had started a pre-med and a nursing program at SLU, at around 2 AM. Got stopped by a friendly police officer who told me how to get across the river and instructed me to do so ASAP. Scary as Gary.
