Mostly I'm tech support to SWMBO's hobbies - keeping the CCTV in the birdbox running (and getting better performance than her pals over at the nestbox forums for considerably less cash outlay :lol: ), making it all easy for her to lift out the photos she wants, etc.
Also I get to take the wee man to all the educational & cultural events and museums (Sea Life Centre, Deep Sea World, Kelvingrove, Edinburgh Castle, cBeebies Live :roll: , Museum of Flight, Scottish Seabird Centre - Gannets!! :lol:, arranged an ascent of one of the support towers of a well-known suspension bridge for him too
)
When I'm not busy with all those and I'm not having a shave or asleep, then I often found poking about in electronics repair and construction, photography, stargazing (I'm no astronomer - I know my way around the sky, but Sir Patrick has no danger here), fell/trail-walking, wildlife watching & wild camping when the need arises. (If you do this, buy a Kelly kettle - they're absolutely amazing bits of kit).
