The weather here today was pleasantly warm, (29C). I took Emily the A10 for a bimble around the area. I stopped to check everything was OK and noticed that the oil tank cap was missing! I'd been checking and topping up the oil before I left home and had not screwed the cap back on. "Oh bother", I thought. "Do I have anything with me that I could put over the tank neck?" Owning a dog, I always carry poo bags in my back pocket. I placed a folded bag over the neck. I didn't think I had an elastic band in the tool kit. A few years ago I stole a comical bag closure from the kitchen and put it on the handlebars. It's a boggle-eyed face with a very long tongue that goes around the item and pokes out of its mouth. Today, he saved the day and held the bag in place until I got home. When I got home the cap was laying on the drive.
