About those bikes...do you have to return them to same "bike station" that you took it from, or can you literally just take one for the quid and cycle it to the nearest bike-lockey-dedicated-station (I don't know what to call them) at your destination?
I think you can return them to any because I heard reports that they were all ending up in the same places and they had to load them on to lorries to get them back to where they were needed. i.e train stations
