Last few photos needed for challenge

It's nearly a year since I started my photo challenge of taking shots of all the numbers between 0 and 100.  It's been great fun to spot the numbers and the whole family has got involved.   The resulting set on flickr is a great summary of the last year, all I need to do over the next fortnight is find the following... 74, 76, 78 and 83 to complete the set.  The subject should be relevant somehow to my year or places I have been - bright ideas and suggestions gratefully received on subjects or events I should get along to.
