A thank you to Manchester
One very good idea at this conference has been the issue of a delegate travelcard to people attending which gives free travel on local public transport in Manchester - buses, trams, and trains - for the duration of the conference. Presume the justification for this is that it means delegates are not adding to the congestion in the city, already exacerbated by the road closures around the conference centre made necessary by security measures. But it's certainly most useful for getting from one's hotel to the conference and back.
