I recall by repute that Columbia, MD, used to be quite the Yuppie enclave once upon a time.
Have the demographics changed?
I can remember going to Columbia for high school field trips - late 60’s -
to see the future of planned development - it hasn’t aged well.
A bit. I’m just around the corner from there. It’s built up more. It’s between dc & Baltimore. But, still is a visually nice area due to all of the regulations.
I live here. Its still suburbia.
