I know enough about Britpicking to know that we're pretty much all "Yanks" who live in the "Colonies," and the usual lift, torch, boot, bonnet and flat -- but I'm Texan by birth, Californian by upbringing, scarred for life by 13 years in South Florida and currently a happy resident of Georgia. I'm not sure if I could even get regional American usage perfectly accurate with that background, let alone Britpick. ;)
