Uber announced the free rides to users this morning. The fine print says the offer is good for the first 500 users who sign up using a special promo code. You also have to be at least 21 and it'll be free if you're already sort of nearby, but if not it'll be a nice discount, anyway.

Note - that's a screen shot, so the promo code bar isn't live. Sign up (and hustle!) to be eligible.
