What other hobby...

My first love, drag racing. Never the same conditions at the various tracks you go to. Constantly tuning for power and tuning for how much power the drag strip can handle on any given moment. Upgrades or reconfiguring of your race car to stay on top and beat the competition 

Try settling on that "perfect" set of guitar strings. Then do it for six guitars. 

For those of you with more than six?  My sincerest condolences. 

Driving my Airstream across the USA and Canada, getting off the Interstates and photographing it with Leica and Hasselblad. Building furniture when at home. Not having a boss or a clock. Drinking wine. @coasttocoastphotoatl
