Even before his suicide at age 67, celebrating Hunter S. Thompson’s larger-than-life personality was an obsession for many of his fans. As one of Colorado’s most famous writers, the gonzo journalist and author of “Fear and Loathing in Las Vegas” built a mythic persona for himself on his 42-acre Owl Farm in Woody Creek, where half of Thompson’s remains were ceremoniously blasted from a 150-foot-tall cannon after his cremation in 2005. But a flurry of activity surrounding Thompson’s estate — including a new film being produced in Colorado this summer, plans to open Owl Farm to the public, a potential touring museum exhibit and Thompson’s prescient political writings — is re-igniting the debate over whether the writer’s famously drug-fueled lifestyle overshadows his influential work. “This is going to be a big year,” said Thompson’s widow, Anita, the founder of the nonprofit Gonzo Foundation and who has lived at Owl Farm for the past 17 years.
