Blackberry's

Today we went to my daughter and her friend with son, they have holiday in Bakkum at sea.
We had a very sunny day, and first we get to the sea for coffee, then the boys get fly a kite. So much fun!

Then we went to the dunes, because the blackberry's were ready for picking;
this is my daughter Manon, she showed me about 2 kilo, now she is making marmelade of it.

Can you believe at the end, I have big backtrouble?
