SG1 investigates the abandoned RV after 'Spirals'

 Sorry about the previous post.  This one is for a specific story, one I thought I had.  I've searched my files for 'RV', 'picnic', and 'chainlink', with no results.  It's a Stargate crossover, taking place after the fall of Sunnydale.  SG1 is looking into the crater and an RV found in the desert with traces of medieval weaponry inside (and a certain pink stuffed pig).  Knowing the team is getting close, Willow arranges a meeting.  (I'm seeing a school bus sitting near the fence surrounding what was once Sunnydale, and the two groups sitting around a picnic table and benches.)  One of the young newbie slayers has abuse issues and attacks Teal'c, sensing Junior.  Faith (I think) knocks her out.
