Coincidentally, i was at Target today browsing the selection of Sterilite containers, and dreaming of large minibogs. *Unfortunately, they're mostly too deep. *But i haven't ruled them out!
One thing to keep in mind when setting one of these up (especially a big one) is that most of those sterilite containers are probably not UV stabilized. *A few months exposed to sun and... crunchy plastic. *Yummy.
I think the colored ones are more likely to hold up, though.
