This year, when the Tesoro Foundation organized its annual 1830s Rendezvous at The Fort, it had the foodie in mind. In addition to its re-enactments of mountain men and kid-friendly educational activities, the festival has added the San Isidro farmers' market. Colorado's classic Southwestern ingredients--sweet corn, roasted green chiles, pumpkins, and squash--will be on sale. And, the South Dakota-based Intertribal Bison Cooperative will be taking orders for its traditionally raised buffalo meat. Saturday-Sunday 10 a.m.-5 p.m. $6. 19192 Hwy. 8, Morrison, 303-697-4771
