into the cement mixing tray full of pea gravel
I have looked all over this planet/internet for economical trays only to find the price and shipping was, at a MINIMUM, over $100 per tray. I am off to my local hardware store where they have 3' x 4' x 10" heavy plastic trays for.............ready?.............$19.99 :thumbsup:

Best of luck.
