- MAIN | NEWS | NEWSLETTER | HISTORY | CONTACTS | OTHER Welcome to MD2600, the official Maryland branch of 2600. We hold our meetings in the Barnes and Noble bookstore in the Inner Harbor in Baltimore. We meet on the second floor, in the cafe area. If it's nice out, we're often out on the balcony, because lots of members smoke and because there's a power outlet outside for laptops and such.md2600.net
