Writer Ken Kesey famously chronicled his exploits of the '60s in The Electric Kool-Aid Acid Test, a book about the cross-country trip he took in a school bus he christened Furthur. Fifty years after that venture, Kesey's son Zane took a bus named Furthur on the road with a new band of Merry Pranksters. It traveled some 15,000 miles in 75 days. With never-before-seen archival footage shot over the course of three months, the movie Going Furthur documents the younger Kesey's travels. At tonight, the Kent Stage hosts the only regional screening of the movie. The bus will make an appearance too with George Walker, one of the original Merry Pranksters, at the wheel. A special Q&A with members of the cast and crew follow the screening. Singer-songwriter John Welton performs after the screening too. Tickets are $12. (Jeff Niesel)
