Big trucks. I presume someone is building a house or some-such on the street behind ours which means several big dumper trucks, scaffolding lorries etc. attempting to navigate a steep hill, narrow road, and tight t-junction with parked cars on it (it's a private lane with no double yellows, and their parking is on the junction itself). With the usual hilarity (and running over our verge in the process). I know the vehicles need to get up there, but they're just too big. Hence several times this morning, the annoying beep-beep as they try and align themselves to get around the corner, wheel spins because they're unloaded and the hill is that steep, and then reverse what must be a good 300 metres to their destination (they're going to clunk someone's car back there, if they haven't already). I should go up there and see what they're actually doing. Oh the pile of stones and crap they leave behind, and branches from overhanging trees etc.
