This is a true story. I'm curious what others might have done so I thought this might be a fun way to find out if I'm of sound mind or a looney-tune

Scenario: I am near the end of a mid-fall bike ride on a sunny Sunday afternoon around 4PM. I am riding a modern carbon road bike with just a couple of water bottles and am wearing cleats. I am on the final stretch going home: a 2.5 mile flat and winding road along the shore of a lake (a very nice way to wind down). About half way through this last segment there is a blue Bridgestone RB-3 in pretty decent shape - and that appears to be roughly my size - on the side of the road with a paper sign attached to it that says FREE.

So...what would you do?
