It's so difficult...he's inclined to buy himself anything he wants/needs. He's 52, so has a lot of stuff already. Can't get anything related to his biking hobby since I don't know enough about the gear involved.
Last few years we went on short city break with kids, but we're stuck at home and no travel while DS recovering from sports injury.
I'm thinking this birthday gift thing is silly for people who've been together for a long time!
