Ask HN: What should I plan to do on a 6 month sabbatical?

I will have 6 months off in the spring for a sabbatical. I've been working on a list of things to do during this time. I am constrained by a wife/kids so this won't include a 6 month trip to Thailand or anything. I've considered the obvious, work out more, hike/cycle more, etc. Any other suggestions/recommendations? I'm looking for tech stuff like projects/books/etc but also non-tech stuff as well. I don't want to spend 60+hrs/week at the laptop like I do now.

EDIT: here's my list so far: fishing and fishing knots (I have my grandfather's gear, but lack his skill), cooking more, learning to make great bread, raspberry pi projects with my son, reorganize/layout my garage, improve my golf skills, reading, explore trails I've never been on, visit friends & family (travel), camping/backpacking
