Do not, under any circumstances, mess with this woman!

"Beware the pink Barbie horn," says Kerry Foster. "If you cut me off I'll hunt you down."

Foster was part of the crowd at last night's Buck-a-Litre bash at the Water Tower Inn, organized by Citizens for Sustainable Transportation.

And Foster, a Valkyrie if there ever was one, was offering up free assertiveness training advice to her more timid cycling counterparts.

"If someone cuts you off, ride like hell until you catch them at the next light," she said. "Then park your bike crosswise in front of them until they roll down the window."

"Then, in your most demure tone, tell them you aren't moving until you get an apology," she said. "Even if it takes three or four lights and the traffic is lined up for blocks, don't move."

"So far, I've gotten at least eight apologies," said the performing arts instructor and designer of the infamous 'Kiss my Axle' t-shirt.

Foster was one of the people who got in line to sign up for the 'Burn Fat Not Gas' campaign and inscribe her sigil on the petition to ban drive-throughs in Sault Ste. Marie .

The event was organized by Andre Riopel and Citizens for Sustainable Transportation which offered anyone arriving at the LoneStar Bar and Grill on a non-fossil-fuel burning mode of transportation (winged horses and wolves included) the opportunity to buy a symbolic litre of beer for a buck.

While Riopel's party didn't make a lot of money for the cause, it did push-push a lot of smiles as hard-core cyclists who rode in on freakish contraptions traded war stories with fresh-cheeked neophytes on shiny new bikes.

Leading the charge of the storytellers was Foster, who regaled rapt riders with stories including one in which she was slapped on the backside by a passing motorist.

"I swear, if I could have caught that guy, I would have killed him!"

Foster said she chased the ass-slapper five blocks before he escaped.

Riopel said he will presenting the drive-through petition to Mayor Rowswell at an opportune time and that His Worship better be listening for Kerry's pink Barbie horn.
