I saw this a while ago, but the program was closed at the time. An incentive program has been suggested various places as a way to help balancing problems, but I can't say it doing very much. I'm going where I'm going, and either there are bikes or not, or parking or not. Since balancing issues affect whole areas, a little adjustment in my travels won't change anything. I'll still start in an area with few or no bikes, unless I'm going against the flow anyway. Does it have to be a completely empty station and a completely full one? Mostly empty and mostly full don't count?
