Directly across the Medina River from the Toyota Manufacturing Plant sits the Land Heritage Institute, a 1,200-acre tract rich in history and archeology. (See “Applewhite bears more fruit,” January 9, 2008.) For “The Nature of Place: Land Art/Land Use,” the LHI has organized artists, curators, archeologists, writers, and anthropologists to explore the theme of “land” in myriad contexts. If this sounds like too much learning for a weekend, you’ll be happy to read that there are leisurely hikes, hayrides, and an hour break with the option of purchasing a box lunch for under $10 . Free, but registration is required at eventbrite.com/event/441421303. Free shuttle leaves Blue Star Arts Complex at 8:30am sharp on Saturday and Sunday, 116 Blue Star, for more info and directions visit landheritageinstitute.org.
