'Things to do' for uncles and dads

[shoppingbagsundereyes]

I'm looking for ideas for my uncle and step dad under the heading 'things to do'. Thinking along the lines of sudoku book, that kind of thing.

Lego do an architecture range with models like Big Ben, the Empire State Building and the White House. In grown up black boxes so great for adults as well as teenagers. Have bought several in the past for adult male relatives and they have gone down great.
