Stuck in traffic

So I was hoping to get out this evening and get some shots - but on the way home the traffic ground to a halt - with emergency vehicles screaming past I was sure I was going to be stuck there somewhere between Rogertsone turn off and Morrisons round about all night.

But then suddenly it was over and we were off after about 30 minutes - still don't know what was going on as a cyclist that passed us said that there was no accident it was a training exercise.

Who knows?

Anyway the cloud above was amazing
