"Speeding Kills Bears" signs

There are seventeen "Speeding Kills Bears" signs along park roads this week, including two between the Big Oak Flat Entrance and Crane Flat. Each year, these signs get placed along roadways where a bear has been hit by a car. They serve as obvious reminders that there is a high frequency of vehicle-animal collisions in Yosemite. July, August, and September are the peak months for bear-vehicle collisions. Please obey speed limits and scan roadsides while driving to ensure the safety of bears and other wildlife.

    @Bernadette, we use standard metal road signs screwed to a A-frame style barricade. We chain them to existing road signs with a special technique that has reduced (but not eliminated) theft. If you have more questions, please contact us using the contact link (above left, or

    I'm a board member of Friends of Griffith Park, a non-profit that works to conserve and preserve L.A.'s largest and wildest city parks. The park is currently experiencing an epidemic of deadly collisions between speeding drivers and wildlife--particularly deer and bobcats. Friends of Griffith Park would like to underwrite a "speeding kills wildlife" signing program modeled on Yosemite's. We have researched available sandwich board signs and have yet to find a sturdy metal sign similar to yours. Can you tell me is your signs were custom-made or if you used a major supplier and also how you deal with the potential for their theft? Any info you can share would be appreciated. Thank you, Bernadette Soter Friends of Griffith Park
