Thompson to play in US Open Qualifier

My parents spoke with Michael at Zach's graduation and report that he will be playing in a Sectional US Open Qualification tournament. It's a 36 hole, 1 day event. The top 20 players will qualify to play in the US Open. Michael got to skip to this last round of qualifier by making the cut in last year's US Open. Of the 13 sites holding a qualifier that day, I'm not sure which one he's playing in.
