Rick I was posting while you replied again. Saving the clay for a new raised bed is a great idea! I actually have TONS and TONS of river rock that the previous owners had all over. I really want to use it to create a border for a raised bed. My husband poo pooed the idea saying it wouldn't stay. But it might work using the clay as bonding agent!
I won't tell you what I used to do with the clay after I bagged it up
