I attended a workshop at Banff International Research Station last week. The setup there is very conducive to productive work, although there is too much good food available (and because of the signs about bears, I didn’t do any any serious walking). The  workshop itself was very well put together with a lot of interesting talks. Really good video of talks is available. Thanks to the organizers Mireille  Bousquet-Mélou, Stephen Melczer, Michael Singer and Marni Mishna and to the participants.
