On Tuesday President Barack Obama just visited the CU-Boulder campus. Now, it's the First Lady's turn to visit Colorado. On Monday April 30, Michelle Obama will be heading to Colorado Springs to speak with a select audience at a volunteer appreciation event.

But there's a catch. The president's speech was open to any member of the public who got a free ticket -- but to see the First Lady, you must sign up as a voter-registration volunteer on April 28 or 29 to be entered into a sweepstakes. And spaces are limited.

Here are the rules, as laid out in a press release from Carrie Doyle, the state director of the Colorado Obama/Biden campaign:

Sign up and complete one voter registration shift during the National Voter Registration Weekend of Action this weekend, and you'll be entered for a chance to attend the First Lady's event in Colorado Springs. We're giving away 10 tickets statewide and each ticket comes with a plus one."

Registering voters is simple, effective and critical to re-electing the President in November, and now that we have a clear opponent, it's time to step up and take action. Sign up for a shift today to join fellow supporters on Saturday, April 28th or Sunday, April 29th. We hope you'll be one of the lucky volunteers to join Michelle in Colorado Springs.

To enter the sweepstakes and sign on as a volunteer this weekend, go here and click this for a complete list of rules and eligibility.
