I live in NYC, so I can see all the flags over at the UN if I really want. When teams scrimmage at my arena, I can just grab their country's flag from over there.
I actually have a preference for away games, personally, since those games will play out earlier than in the New York time zone and I'll see the results sooner. (Every now and then I change my Training if the minutes didn't play out as planned in a scrimmage, and the sooner I can see this the better in case I can't get online on Thursday night.) If suddenly Supporters will only want road games to collect a flag, that will make it a little tougher for me to get road games in those hard to schedule countries where the most active teams are mostly Supporters.
Don't ask what sort of Chunks they are, you probably don't want to know. Blowing Chunks since Season 4!
