Very fun event, as always.. glad it didn't rain, that woulda made things fun, but way too messy
Oh, and I know exactly where the tire is.. THE FUCKING DUMPSTER
If you'll take a look at the pictures, you can see that the problem wheel has the word 'BENT' written on it; hehehe.. yeh, that was from the first event

That bent, yet lead-assisted-balance wheel, went on to see another event at buttonwillow, and an event at streets of willow..
This last event, however, I'm pretty sure that wheel had at least one, two... four? run-in at a bad angle with a rumble strip.
With the wheel off the car, I noticed the largest lead weight was.. no longer attached.. doh.
The breakaway of tire-from-tire was really progressive.. at first I thought the subtle rustle was an old truck driving nearby.. after looking around and not seeing anything nearby, and then beginning to feel a complimentary shutter in the rear.. and then finally the noisy breakaway.
Thankfully it wasn't on a steering/braking wheel.. then again.. i might have felt it coming across in the steering system earlier.. ohwell. And i'm surprised it didn't happen at the track.. the speeds at times were about the same.. ~80mph, or so
