Had a bit of a "moment" today

Was lashing down something chronic, mirrors soaked with rain, was reversing onto this customers drive, and in the mirrors it just looked sloped - couldn't see the steps at all! Was only going about 1mph or less and all of a sudden there was a great big jolt and a thud
Couldn't get it out at all, as the drive was complete shite - made from clay and sand, with all the rain it was water logged. The flag stones were cheapo sandstone that just cracked and crumbled, and cos it was on a downward slope, with all the rain I couldn't get any traction to the front wheels, so it just sat there and span whilst the rear wheels sat against the "step" of clay
Had to wait 2hrs for recovery man to arrive and winch it out
