My dad and I came upon that long line of parked cars and bikes and people standing around outside their vehicles and knew it had to be bad. I think we were only there about 45 minutes. Sucks to be the Miata crew who gave up after 2.5 hours and turned around; unbeknownst to them, we started rolling about 5 minutes later.
I heard about the two Zs, and also the biker and the van. Didn't sound good for the biker...
