It's wasn't a sonic boom you heard over Boise at about 1:30, it was me "Popping" in the Snake River Handicap on the King hill climb on the last lap. Tom did great. I actually did well also. Very please to finish the RR season this way.
Video coming soon.
Looking forward to the video!
Looks like a great race, and can't wait to see the video.

I think the popping noise was my sweat sizzling or the boiling sound in my water bottle as it evaporated before I was able to swallow it. By 1:30, things were heated up alright.
