Cars!

Went and sat by a busy intersection.  It took about 8 minutes for Rigger to move away from me and start exploring.  But after that he was mostly good.  Sniffed, explored, chased the whip toy, did some personal play.  Stayed out for around 30 minutes total.  Saw cars, busses, a car-carrier, motorcycle, and heard either a motorcycle or muscle car.  Loud and obnoxious!  Also saw several people walking dogs, which Rigger either was interested in, or avoided (big bulldog that was lunging and not dog-friendly, from how the owner was acting).  He would occasionally stop and watch the traffic, but then went back to playing.
