Share '4.0 drill groups and Indoor clubs in the baltimore/columbia/ellicott city area'

Does anyone know of any indoor clubs in the baltimore/columbia/ellicott city area that run drill groups for 4.0+ players? Am looking for something I can drop into once a week (after work).  OR if any 4.0+ players are able to get indoor time and looking for a semi-regular hitting partner I'm open for that as well.  Thanks in advance and hope everyone is having a good start to the new year!
