Went with O&J to the Kröller-Müller Museum. It's a fabulous art museum in the middle of a national park - de Hoge Veluwe - about an hour by car outside Amsterdam.

It is a beautiful park to be in - plenty of nature, deer, a sculpture park, pathways, forest, fabulous Museum, lakes and sand drifts. All to be experienced by white bikes. Except we didn't.

The white bike policy is a community-spirited affair. There are free, unlocked bikes for use, standing at various points in the huge park. You borrow one, cycle to your next destination within the park, then put the bike in the bike rack for someone else's enjoyment. In theory.

We walked from the car park through the forest to the Museum, as all the bikes were gone on such a fabulous sunny day. No biggie. But when we went to collect a bike after our wander through the sculpture park, we discovered some of them were locked. Cheeky minxes. Some selfish bastard had brought their own bike lock to secure four, five bikes at a time, to ensure they had bikes for the next leg of their wanderings.

Kind of defeats the object of the exercise. However, even that and the 45 minute queue for the cafe couldn't spoil a top day. O even wore a hat.
