Highly doubtful that the guy riding it was the one who stole it out of your garage. But certainly would've been nice to ask him where he found it, or if he bought it and from whom.
This is pure speculation but I think it may have been the same person.
Talking with the town police, my dad (who was on the force for many years), a riding friend that is on the force, and the posts from you guys they kept saying it was targeted.
Recounting things that have happened that last couple of week I had a delivery last week (a couple wheels for the Ram so good size boxes) that had a FedEx driver and a trainee in my driveway for a long while I was in the garage working and went out after a few moments to see what was up and I could see the main driver giving instruction to the trainee. They were nice and brought the 2 good size boxes to the front of my garage (although I didn't ask them to). The main driver was fine but I had a weird vibe from the trainee - I felt he was looking over my shoulder into my garage where of course from that angle would be the perfect view point of the Bronson on the Park stand. My street is a dead end with a handful of houses. And my garage is set back pretty far and hard to see what is inside from even the middle of the driveway. Landscaping and cars blocking the view.
This bike isn't highly viewable. It's transported in the back of my truck with only a grip poking out the back for quick trips to Huber or Hartshorne. TBH - I do more hiking and TM at Huber/Hart than ride this bike there haha.
Add to that my DJ bike was by my side door so if someone wanted a quick grab that would have been a lot easier (although still not visible from the road).
So if he was dumb enough to go ride it at Allaire (like I said to someone on IG - like riding a stolen Harley to a Hell's Angels bar) he might be the stupid enough to steal something he saw while be a trainee for FedEx. But this is purely speculation.
