That is a superb list for the challenge, very well thought out and the pictures do work very well to go with it - I agree with your points at the end, it has to be much easier to make these lists up when you are free from commitments - I thought it would be easy but when I came to it I really struggled - because most of what I would have thought of would have been totally impossible, and my own feeling is these lists should at least be achievable - even if you never actually do getting around to do it.
You nailed it that was my thought process as well they had to be achievable
A short achievable list is far better than pipe dreams
