Acro-groups you have seen?

In my short life, never really considered going specifically to an airshow just to see a certain group, I have managed to see…

– Canadian Snowbirds(Tutors)
– USAF Thunderbirds (F-16s)
– RAF Red Arrows(Hawks?!)
– YugoslavAF Letece Zvezde/Flying Stars (Galeb G-4s)

Where, in North America, can I get a chance to see a Russian team, like Russian Knights?
