Three pairs of trousers

I took Jasper for an early walk before the Rally (Catalunya) began and got soaking wet with the rain.
Changed trousers.
We walked up the hill to where we could watch the Rally and got bogged down in some seriously sticky mud.
Changed trousers.
Shortly I'll be taking the dog out again and it's still raining... but I'm not going far so I hope I can avoid a fourth pair of trousers!

p.s. the clouds were much more interesting than the cars!
