Interesting, Jacobson warned against doing that very thing -- dusting stuff with pepper powder --  during his lecture at 'copia!  He said bears don't like pepper spray, for sure, but black bears get used to it, and actually like to lick pepper off things.  He said grizzlies and polar bears never get used to pepper spray.

Good thing, far more dangerous.

PB, Thanks for the info.

I do more like what S_D says in practice. Just thought the cayenne idea would work. Never tried it.

PB, Did Cliff mention Bipolar bears. I hear they can be unpredictable. ;D
