My main hobby appears to be wasting (oops, I mean spending) time on CT.
I like to hike and get out into wilderness for at least a couple weeks every year or I go nuts.
I serve with a local nonprofit group trying to clean up (demolish or repair) the dilapidated houses and buildings that plague our otherwise-gorgeous area.
I'm taking a break from it right now but have spent 20 years or so as a volunteer advocate for children who are abused/neglected.
I'd like to say I'm learning to play guitar but it's more like I feel guilty that my guitar (b-day present from spouse a year ago) is sitting in the corner looking at me reproachfully.
Am (excruciatingly slowly) rehabbing a house for rental and I usually take 1 class each semester (usually science-related) just to keep the brain working.
Then there's the job that pays the bills, and the cows that spend the above.
