JUCO recruiting question

The coaches have said that a lot of guys in the 2003 class got their first exposure to SMU by coming to a Junior Day and/or SMU's camps. With the announcement this week by Coach Bennett that he'd like to take "3 or 4" JUCOs a year, I'm curious: are we allowed to have JUCOs on campus at any time for an early look at the facilities/campus, etc? I would assume that if they're enrolled at Junior College that they wouldn't be allowed at Junior Day or in the camps. But is it allowable to schedule a JUCO Day or something?
