Using Campaigns

I'm participating in several NetWork After Work meetings in my city. They meet once a month, and sometimes I see the same people there, but usually it's a whole new crowd.

I'd like to keep track of the people I meet at these events, and which date. Would I create a different "campaign" for each event on each date, or is there a way to make one campaign repeated on multiple dates? Or maybe there's just a better way to track this. Any ideas?

Thanks,
