There's a lot in the skies

Remember when the Icelandic volcanic ash grounded all the planes and there wasn't a con trail to be seen in the sky over Britain?

This morning the sky above our back garden was full of crossing lines - difficult to distinguish con trails from clouds.

It's hot as b****** but I'm going to Zumba anyway in the hope that getting my muscles super-warm will enable me to ease out the pain in my right shoulder (possibly caused by over-use of a computer mouse). I'll be a puddle on the floor by the end of class!
