I'm learning to hunt with rifles, because if you think about it, hunting gets you the healthiest meat - organic, free-range food. It's a totally yuppie spin on what I thought was kind of a redneck occupation.
I'm a big, big blues fan and the last several years I've really invested in the blues a lot, and I think my playing is getting better because of it - not necessarily better on a technical level, but certainly on a level of appropriateness.
