Mike,
Sorry I didn't see your post in time. It blew from 10:30 to 3:30 and was still blowing when I left. Solid 7.0, 82L board, I could have probably gone to 6.0, but enjoyed the extra power in the lulls. Very rarely underpowered. You gotta love Utah lake on a North day. Wow!
I just checked the website and it never happened at Provo Boat Harbor. That is weird. It was just a North Utah County wind event.
