No Questions Asked

My bike was stolen off my front porch yesterday along with two of my neighbors bikes.  Pretty ballsy to steal something off my front porch, especially when a lot of my neighbors are home all day everyday. But I have a feeling I know who it was.  I've felt like my house was being staked out a few days ago by some thug kids. By thug kids I mean kids in their early twenties with no jobs.  I want to post some "Stolen bike" signs around my neighborhood and post a reward... no questions asked. Then first thing I would do if someone came forward to return it is ask them why they stole it.  I'd be like, i was kidding about the no questions asked part.... and the reward part.  And then punchasize their face... for free.
