Chemical Spill? What?

I just got a text message from my gym saying 'Daivd Lloys closed for the day due to chemical spill, so classes cancelled. Thanks'
What?
That is SOOOOOOOO strange. Shame too cause I was really looking forward to going to that class tonight.
I guess I'll walk home part of the way instead - past our new place! I want to time how long it will take. That is IF it doesn't rain!
The count down is on - only 10 days until we move!!!!!!!!!!!
