I'm 44 now, but when I was in my teens I was a water ski instructor and was a member of a ski team in Nova Scotia. We practiced 5 days a week and performed at many events...needless to say I was on the water all the time!
The biggest pyramid we ever made was 6 person (I was never a petite girl, so I was either in the middle or on the bottom of the pyramid

) I know the coordination that had to go into building a pyramid of that size...I can't imagine building one with 44 skiers. How exciting!
I'm so sad I had to give it up...I'd give anything to be able to ski again, but don't think I'd be able to ski with my cane.
Congrats to all the participants...exciting!
