PIERRE - The Pierre City Commission has approved the route for a convoy of truckers who are upset by high fuel prices.

An estimated 100 to 200 truck drivers will stage the demonstration on April 28.

Brian Frahm of Pierre is helping organize the convoy, which will pass the state Capitol.

He says the convoy will include semi tractors only, not trailers.

Frahm says it'll be an orderly event, and none of the trucks will enter the Capitol grounds.

The truckers will gather later at a local park for speeches.
