Look out for the Bull

I have a week off work and I am at a loss as to what to do on Tuesday, the Delightful Mrs S is working and has "allowed" me to have the car. I therefore plan to dump her off at the office and them drive on down to the Darenth Valley to run the river and then nip over to a small conurbation called Riverhead to then cut into Otford to take on a humongous hill at about 9 miles. At the top of that hill lives a bull, a huge bull.......wish me luck :-)
