Yes, apparently they just arrived:
Red Bull Racing sure is good at not publicizing this sort of thing, so that very few people know about it before the last minute and therefore very few annoying fans show up! Well done, RBR.
Anyway, I have no idea what (if anything) they have planned in the city or whether they are just on their way somewhere else, but I thought I’d mention it in case (a) anyone is interested and (b) anyone has further details.
