Two days into Sundance and it's already apparent that there's not enough city buses and shuttles to handle the hordes of festivalgoers and winter vacationers. Traffic anywhere around Main Street is a nightmare, and I don't recall ever seeing so many buses flashing the "Full" sign. I've taken to walking to venues whenever possible, and the slight increase in temperature ( teens-to-mid-20s) makes that even more of an option. Some of the drivers are already in mid-festival cranky form, but the tunes have been interesting as we've already heard a so-loud-it's-distorting Violent Femmes' "Blister in the Sun" ( a bus sing-a-long!) and a pretty cool Depeche Mode instrumental remix on the first "Techno Bus" of the year. Motor on...so far docs are trumping narratives, but more on that later.
