I met a group of horses and riders while cycling slowly up hill on a bridleway.
The one at the front saw the bike and started prancing all over the place, which set a couple of the others off.
I waited until they had lurched over to one side and quickly darted through on the other side.
Later, I came back down the bridleway at high speed and saw the same horses ahead of me, unaware that I was behind.
I wasn't going to risk having one of the stupid things jump around in front of me again, so I hammered through and got past before they realised what had happened.
I could hear the shouting and commotion behind me, but I was long gone by then.
Horse, dog, bike or car. If you can't control it so that it's not a danger to other people, don't take it out in public.
