Since Friday the air traffic in Germany and most of Europe has been grounded thanks to the eruption of the Eyjafjallajökull.
Some people still get their planes up into the air, even though, sadly, no passengers in those (unless they are really, really small)
In order to get off the ground, some people just climb up into the trees
(here in my home town a tree climbing garden has opened a couple of weeks back - it does look like fun)
And, Spring has clearly - finally - arrived.
