All the coffee shops shut in Maastricht

On the 1st May the authorities restricted the sale of cannabis to Dutch residents. The coffee shops reacted by shutting down for "renovation" work. Meanwhile illegal dealing is taking off on the streets as a result.

I've been thinking about my rubbish collecting project on the Maas. While looking through a sailing book I noticed a type of net basket used for carrying things in. The frame is an upturned U-shape with a net suspended in the river channel, the opening of which faces upstream. The idea is to catch enough rubbish in the net in order to drag the U-frame from a vertical to a horizontal position. This would automatically close the net entrance. The filled net could then swing toward the river bankwhere its contents could be emptied into a container barge, or simply left to be collected.
