Ha! My son took our bikes, so we could together do Cross of Greet and Bowland Knotts, on his car roof but we arrived late, the weather was grim, he announced he had to get back quickly to pick up his son from school, he had told me the wrong bike to bring and he rode virtually the entire ride 300 yards in front of me.
For nine months afterwards I refused to ride with him although the following week I went back on my own and enjoyed the ride by not having to wonder if he had completely disappeared back to his car and left me behind!
