I love to cook when I get time to. Just knocked out a delicious meatloaf yesterday.
Other hobby, oddly enough, is my job - I'm a fire direction chief in an airborne field artillery unit. Jumping from a plane at 1000 ft in the middle of the night with 150 lbs of gear strapped on, then pulling out charts, firing tables, protractors, etc and doing a bunch of math so we can blow something up 5 miles away is a good time, as far as I'm concerned.
