That's getting to be almost anywhere you go now, in my opinion.
I know two detailers from Greater B'Mo that have a set group of regulars and not looking to add more. When I was a kid, I used to relish the thought of our summer vacation to DC/B'Mo just to see all the blinged out 442's, Rivieras, Roadrunners, etc. ~blue collar cars.
Back in the 70's, that area was inundated with blinged out Dodge Darts and Swingers...something we did not see much of in SC.
I wish I had more local guys to detail and exchange ideas. Most of the ppl in my neighborhood consider detailing running it through the touch less wash and drying it. Including my wife who's from NY lol
