Here's the question you should be asking -- does the reason for having the risk reduction rules in the first place continue to exist during the Summer?

It sounds like there's at least an equal opportunity to run afoul of those rules. It sounds like there is drinking, etc., so why would you not treat everyone exactly the same as you would during the school year?

As far as what actually happens, that's going to vary from place to place, but if I was an advisor or something other than a meddling alumnus, I'd probably want to strongly encourage everyone to continue to play by the rules whether they're being enforced by the University or not (because if something bad does happen, you can believe the university is going to want to do something about it, not to mention your HQ, etc.)
