The city of Columbus plans to use fireworks and lasers to scare away the geese officials say are thwarting efforts to develop newly widened Olentangy River banks. The 100 thousand dollar plan follows unsuccessful attempts to get rid of the birds using a plastic coyote, fences and chemicals. The new eradication effort begins shortly before sunset Wednesday with the detonation of fireworks over the river between 5th and Lane Avenues. U.S. Department of Agriculture teams will also point lasers near the geese, which the birds mistake for predators.
