Anywhere near Towson for smoothie/pastry sours, like RAR OoO, Cushwa, Shmoojee, etc?

I know Fairgrounds in Timonium carries a very small selection (1-2 flavors at a time) of RAR's Out of Orders but is there anywhere else that isn't too far of a drive?

I'm also trying to find South County Brewing (PA) Automatic Fantastic Blueberry or Blackberry, if anyone knows any leads on those.
