Going to work this morning I saw a free Starcraft pup in front of a house in Catonsville.  I was running late and couldn't stop, but it looks to be early 80's, 10 or 12 foot box, with FREE written in magic marker all along the roof side.  It was closed so I have no idea of the canvas or interior condition, but it looks like it has been sitting in someone's back yard for a while.  If interested, it's on Bloomsbury Ave, right across the street from the Children's Home.  You can probably google it and find directions, or PM me.  It's on a major street, so it probably won't be there by the end of the weekend and since there was no contact info, you'll just have to go there to see it.
