Just had a fantastic ride to take my mind of surface integrals; was meant to be a quick 20 miles but I got lost after about 5, rode on road signs and sense of smell for the rest of the way. Ended up about 30 very enjoyable miles on roads I hadn't ever ridden before.
The pause at the big roundabout over the A14 was me desperately hoping that I didn't need to go on it to get back into town. Fortunately I didn't.
