Guys, There are a few other forum members that go the the Church of the Holy Doughnut which is over in Burtonsville,MD. They have this posted under events NorthEast. This is every Sunday morning from 8:30AM to 10:30AM. The last time I went there were approx 60-70 cars there. Everything from classics to muscle.
I plan to go over again this Sunday. If you need directions let me know and I will get them.

Regards,
