As far as I'm aware, he's only usually in the US for a month or so pre-season - they're currently there for a pre-Worlds camp so there won't be issues with adjusting to timezones etc closer to the competition & did a similar thing in 2011 when it was still intended for Worlds to be in Japan - so there's not really a need for any permanent base. They have a full time base in Novogorsk & there everything is set up properly. That said, you would think that these camps would be planned for far in advance & suitable arrangements made so that there's no need for the nomadic living out of a suitcase lifestyle that other posters have described. It must be difficult for his skaters to deal with the number of people in his training group - he must have been at every GP this season, surely? It seems like they'd only see him in weeks they are actually competing, as the rest of the time he'd be in another country with other skaters. I remember Miki Ando travelled with him to TEB in 2010 and trained at the Bercy rink during the competition, but that's not ideal and probably not even financially possible for most skaters.
