Back on the M6, it was still raining lightly and the traffic was heavier than ever. At least it seemed to be warming up a bit although it was cloudy and grim up ahead. We sat in-line for several minutes until another bike roared past. I cursed to myself. "$#@*, why do I keep forgetting we can do that?" "Are you up for some more lane-splitting?" DewNmoon shrugged agreement and I pulled out into the narrow gap between a minibus and fully-loaded pantechnicon. Lane splitting was faster than sitting in traffic but still painfully slow. Most people saw us coming and moved over to make room. One person in a BMW SUV kept trying to squeeze us out (I thought that sort of behaviour was illegal in Britain ) but we eventually made it past him. I wasn't too bothered about most of the gaps I squeezed The Duchess through but I was trying to keep an eye on DewNmoon who was struggling with the extra width of the Weestrom and I kept having to wait for him. I was getting a bit nervous about all this and it certainly was stressful with the wind, rain and spray, not to mention the fact that we had already been riding in crappy conditions for over twelve hours. A couple of times when I pulled back into a traffic lane to wait, I tried to peer into my GPS screen and see what time it estimated we would get to Land's End. It looked like we were going to be at least an hour-and-a-half late. "Surely we can't have that far still to go?" I guess the challenge was over - and we lost! Well, our alternative was to head for Rattery, which was in the same direction, so we might as well keep going for now. However, my nerves were getting frayed so I decided to play it safe and sit in-line rather than take any risks to save time (too late now). DewNmoon pulled up just behind me to one side. I turned and shouted at him: "Hey! Have you traded any paint yet?" Dew shook his head, then pulled forward to come alongside and gave the back of my right pannier a mighty whack with his left one, shooting me forward a couple of feet. I hope nothing's broken but I'm not getting off here to check. Dew looked at me and gave a "what are we doing?" shrug as another bike, this one 2-up, zipped past us. I guessed he was happy to keep lane-splitting. He seemed to be finding the whole thing amusing and was grinning at me from under his helmet so I gunned the engine, powered The Duchess back into another narrow gap and sped away.
