We're a tough sell when it comes to Facebook, which we consider inherently evil, what with privacy violations and Russians and too darn much power in too few hands. But the state and local cops are making an offer that's tough to refuse. Starting now, Lyft and the state Department of Transportation and police are offering free holiday rides so you don't have to drive while blitzed. By following agencies on Twitter or friending them on Facebook, you can download links to $20 ride credits from Lyft. You'll need a Lyft app to get the freebie, and you'll also have to use either Facebook or Twitter to get codes from public agencies to make it happen. Besides Illinois State Police and the Department of Transportation, participating agencies include the Sangamon County Sheriff's office and police departments in Chatham, Grandview, Leland Grove, Auburn, Rochester and Southern View. There are 1,000 credits available in Sangamon County for use each day from 3 p.m. until 6 a.m. through New Year's Day that will be given on a first-come-first-served basis, so get cracking. And in the fine print department, the state says that possession of a ride code doesn't guarantee availability of a ride credit, whatever that means. Don't say we didn't warn you.
