I've been there most of the week so far as medical standby. Tomorrow I'm at the practice rink in the morning, WF to watch in the afternoon, and sweeping for the final groups in the evening. Tuesday was my long day--picked up the first load of officials at the airport, two more airport trips, helped with set up (accounting, medical, coach's hospitality rooms) plus other stuff. I left the rink at 1am Wednesday, got ~three hours of sleep, then back to the practice rink at 9:30am followed by WF at 1pm. I was one tired woman.
I'm sure we can use extra help with breakdown Saturday if you want to volunteer. I'm sure I'll be there--I seem to live there right now.
