 We hope you will join us for Science Friday, which airs from noon to 2 today on KAWC 88.9 FM and kawc.org. Hi, it's Steve Inskeep. And I'm Mary Louise Kelly. If you believe in the mission of this station, but now's not the right time for a financial gift, donate a vehicle you don't need instead. It's easy to do, and it could mean hundreds of dollars in support. Learn more on this station's website. Visit kawc.org slash cars to begin your donation today.
