Just about all teams are in country. They have been holding closed practices and scrimmages. Starting Monday the practices will be more public.
HDC Teams S Korea, Argentina, Russia, and US U19 and Mexico ( good practice teams) are all playing practice games at HDC...S. Korea played Mexico last Wed, there is a game today, tomorrow, and Tuesday all scheduled right now.
Norway is one of the teams that hasn't arrived in the U.S. yet. They will be leaving Norway tomorrow, but I haven't heard yet if they will be having any open practices in the Philadelphia area.
Canada isn't in the States yet either, of course the team doesn't exactly have far to travel to get from their training base in Kingston, Ontario to their first match venue (Columbus). Canada plays the Australians tomorrow in Kingston at Queen's University, and then presumably will shift base to Columbus either Monday or Tuesday.
