Peg, no forcefield is needed. Buckets are simply smarter, more loyal, choosier critters than heads are. After all, have you ever, ever, heard of someone dropping their toothbrush,hairbrush, comb, glasses, dentures, or knife into a cedar bucket? And then having to worry about plunging into ordure to retrieve it?
Of course not.
Sorry about your economic conflict of interest <G> but, no heads, no indoor plumbing
? No overtime calls for plumbers needed. No cable TV? Never have to wait for the cable guy. Or miss a show when it goes out. No telephone? No slamming on the phone
There's something to be said for the simple things in life. Like cedar buckets. And way way bigger knives 'cause if it's small enough to drop down the head
, as Crocodile Dundee might have said, you probably DO need a bigger knife.<G>
