A friend sent me this link and said he planned to carry one while riding the Tour Divide this year for protection against rednecks and grizzly bears.

I knew he was joking and figured that the product was an April Fool's Day spoof but if you do a Goggle search you'll find multiple websites/blogs promoting it. If this thing is legit I'd be more afraid of the twit who bought it than bears or inbred locals.
