Met up with Aunt Susan (who is here in London on a theater trip) and went to the fabulous new Tate Modern.
One work we saw that we believe had haystacks was Raoul Dufy's The Harvest but since I've broken the hay database, I'll have to wait until I can fix it to check and see if its there already. Hanna and I are guessing that its mostly grain, but some haystacks in the back at least. Alan will know for sure.
Here are some photos of the Weather Project which I thought was stunning.


That's Hanna and I in the middle reflected on the ceiling. Everyone was lying on the floor "sunbathing".
