"My house was broken into while at TOC. They took everything, a lot of bikes,cars, and you name it they got it."

"If anyone out there sees anything you think might be mine, let me know. Thanks...DZ"

That sucks. Unfortunately it might be a little harder to track down one of his rides, vs. a one-off TT bike.
