AUSTIN, TEXAS, Nov 19: Celebrities and well-heeled Formula One fans from around the world hit art shows, book signings, fashion shows and parties this weekend in the Texas capital that is hosting the first US Grand Prix in five years. The glittering off-track events to celebrate Sunday’s Formula 1 race are a change of pace from the gritty, hip gatherings that typically accompany the city’s well-known extravaganzas such as Austin City Limits Music Festival and the South by Southwest film, music and interactive festivals.
