Another good grid. So many possible anniversaries made it tough but do able . Again my advice is to work on the answer acceptance. It can be tough to cover all synonyms but it's easy to avoid insisting on plurals - just use short word stems as explained on the site.

Nice grid, let down by the answers. "Coast" not accepted for the coasts. "Anniversary" not accepted for the "number of years married" group

I agree with the comments left so far. Let a decent grid down.

Not a bad grid - I could tell what the groups were, from fairly early on, and was just lucky that my random guesses at what belonged in which sorted out the last two groups in time. It's a shame 'coast' was not accepted, for 'famous coasts', and 'anniversaries' was rejected when it was a more accurate and concise answer than that given. Maybe be more concise and less narrow in the acceptable answers.
