Day 724

Lovely weather for Easter Sunday but cold. Did various 486 experiments, went round to M's and talked for an hour and a half, about courses, jobs etc. She was impressed by C's front page article in the free paper.
Watched _The Great Escape_ in the afternoon, some scenes cut unfortunately. It's the 50th anniversary of the real one this week.

Did an Excel spreadsheet to calculate the Grand National winner (Southern Minstrel).
