I want to get involved in rowing, where should I start and what should I be aware of?

To anyone who is experienced with rowing:

I would very much like to get involved with the rowing team at my University in the fall. I have never rowed before, however I am in decent physical shape so I feel as though I would be up to the task with some exercise over the summer. Is there anything I should know about rowing specifically, in order to prepare myself for it, so I can jump into it in the fall?
