Fun

Very good. Top Marks

I prefer the more traditional types of wall so this one was right up my street.
Loved the Yellow, Cabin and Millennium groups - wonder if you noticed the opportunity to use Millennium as a red herring for a group based on falcons? I think it would work better with only one word group and then you could have had Black in there as a falcon, a fever and a river. 5 stars from me though. :-)

Less challenging but really good fun.

Easier but still fun

Nice challenge. Well done

Very nice grid!
