Malissa Tayaba, vice chair of the Shingle Springs Band of Miwok Indians’ Tribal Council, steps through an attentive crowd that’s transfixed by a group of dancers in feather-trimmed regalia, following the stringent beat of clapper sticks. Today’s event is the annual Big Time celebration, and it is being held on the tribal rancheria that is also home to the Red Hawk Casino and Resort near Placerville. Tayaba grew up on this slope of government-allotted tribal land.  She maneuvers through the savory vapors of “Indian tacos” (frybread with various toppings) before heading into a maze of blankets, beads, shell jewelry, and fox and coyote pelts for sale. The scene is vibrant, but Tayaba knows that this corner of the oak woodlands looked very different when she was young. Back then, as she describes it, the reservation was just a smattering of trailers with no running water.
