tax revolt

I ran across the yard sign pictured at left quite a few times as I was driving through central Orange County today, particularly plastered along the strip-mall section of Hillsborough along Churton St between the two interstates. Something tells me these folks aren't interested in "revolting" by lobbying their state representatives to allow us to utilize alternative revenue options. Does anyone have any insight about the story behind the signs? Is this a grassroots effort or is there an existing anti-tax group sponsoring this?
