Oooh tractors! Our lovely neighbour next-door works on the land, and owns two or three tractors. His son is an agricultural mechanic/engineer. Sometimes they park a massive, gorgeous tractor in front of their house (Last time it was a lovely red-and-yellow monster with gigantic black wheels.) I drooled, and the dad offered to let me ride in it and have a go at the controls. But I'm too darned old and decrepit to clamber up into the cab. He and my husband pushed my bottom from underneath (providing amusement for the entire street; my face was as red as the tractor) and I tried and tried, but we had to give up.
He said, "Oi reck'n yer tew owld fer this caper, mawther!" My husband laughed so much I thought he'd need an ambulance!

Hedgehogs can be enticed into the garden if one provides corners of wild growth, little 'hedgehog houses' of wood, a compost heap or pile of leaves etc in which to hibernate, and also one can put out saucers of water and small amounts of catfood in a dish. You can tell if one has visited because their poo is very black and a bit sticky (yuk!)
Of course, the food might encourage rats. But they are ever with us sadly...
