There used to actually be Jams at UMD-CP at least once a summer, however the individual that ususallyorganized them (Quetzalcoatl) moved to Boston, and since then nobody has really taken the initiative to revisit the area with a big "Jam". I have jammed there three or four times, and I found it to be a very good campus to spend a day or two traversing. I have actually wanted to revisit it because there are a few things that I could not do the last time I was there that I would like to try now.
Now, if you are referring to UM-BC, I am afraid that I have never been there, so I have no advice for you in that regard.
