All things about music. Guitars, the outdoors, fishing, hunting, history, good food, eithnic foods, cooking, good movies.
Eric Clapton, B.B. King, Bob Dylan, Clint Eastwood, any veterens of World War II. If by magic, all of the greatest musicians that played hard and died young.
Man, where do start! Rock n' Roll (there is such a thing, though many have forgotten about it, especially the "Roll" part), Blues, Jazz, Country (I prefer old country), Americana, hell just about anything that has good songwriting and good musicians! The Pickups. Lucas.
The Outlaw Jose Whales and other Clint Eastwood movies, Band of Brothers, Spinal Tap, Come September, Better off Dead.
The History Channel, AMC, A&E, The Discovery Channel, PBS, Comedy Central.
I'm a big fan of Autobiographies and biographies on musicians, history books, and the occasional novel.
