Dartmoor at this time of year has a very high number of extremely stupid animals, especially near pubs, pull ins and car parks. They can wander into the road at any moment and without warning and are seemingly oblivious to the dangers of a passing motorcycle.
There are also sheep, ponies with foals, Highland cows (great big hairy ones) and other wildlife. They are far more cautious than the walking pole and backpack brigade, but clipping one will still spoil your day something horrible.
