Altadore had one last weekend.
A ton of fun. No damage done.
The worst gymnastics team sleep-over I can recall was at another gym. We picked a night when the Red Hot Chile Peppers were playing in the stadium next door. (Our idea was a sleep-over / free rock concert.)
Unfortunately the kids opened the doors to better hear the music. And concert fans decided to come into the gym. To use the washroom.
We had to evict them quickly.
