one horse power

To Durham to pick up the last of our party my very grown up son and his wife and my daughter.
The journey was quite eventful as we passed loads of travellers with their pied horses. They were gathering for the Appleby Horse fair which is happening next week. It was odd to be driving down the fast dual carriageway of the A66 with warning signs telling us to watch out for horse drawn vehicles.
It was a reminder of earleir days when life went at one horse power 50 horse power and you didn't need a petrol station, only a grass verge, and a lot of patience.
