Watching 3 of my young Muscovy ducks who just couldn't wait for me to rinse, move and refill the stock tank which I'd opened the valve on so it would drain while I did other field chores. They just had to jump into the tank and play in the two inches of water that don't drain out! Of course, once I'd filled it, the geese chased the ducks off so they got first swim - the splashing was impressive!
I enjoy how a tractor can have a smaller turning radius than a van. I think its nice to be able to simply turn around a tractor, instead of doing three-point turns in a van. (context: I was trying to haul small buckets of sand from Arrakis by loading them into a van, and then, I used a tractor!)
