Stumbled on this Aus Post Bikers ACA clip on Magpies. [URL="][/URL] They'll be starting their bomber tactics in the next few weeks and I know how a mighty wack to the back of the head can scare the crap out of you. On a bicycle, they drive me nuts every year, worst attack resulted with a decent cut to the side of my face about 3 years ago. I'd say a full faced helmet helps but a wack to the back of the head (not by a pillion) would still scare you unexpected. Any stories? Or better still, tips that help (sshh, I really want revenge..lol) with these protected birds (national pests in NZ).
