YAY!

Vada is jumping on the composting bandwagon!
The only concern I would have about using the old deep freeze is the freon that might be in it - I know nothing about them, really, other than how hard they are to get rid of -- I had one too, for months and couldn't get rid of it. You could try putting it on freecycle.org before disassembling it (if it's not too late!) and may be someone will come take it off your hands. I wasn't that lucky, though I did try, and a local guy hauled it to the dump for me.
Anyway...! That's the only thing I'd worry about (freon) but other than that it'd work with holes drilled through it and sat on some bricks/etc like Tammy suggested.
I agree with the pond idea - but I can see your point about being nervous with the kiddies around. I would be too.
Keep us posted!

I get so excited when someone starts composing now
