Saturday, I have the honor of being a part of two great things. The first is joining protesters at a rally in D.C. as part of the Tar Sands Actions that have been going on since Aug. 20 in front of the White House.

The second is that I’ll be on a radio show called Mrs. Green’s World. The show airs live from 3 to 4 p.m. EST (noon Pacific). The program is based out of Tucson, Ariz.

We’ll be talking about some of your favorite topics from my column and the tar-sands protests.

You can listen to the radio show when it airs here. Hope to hear from some of you while we’re on the air.

Happy Labor Day weekend!
