Nature provides both the ideal outcome (great weather and lovely-smelling laundry on the clothesline) but also a lot of much-worse scenarios that drive the use of technological solutions. Like a long humid rainy season where hang-dried clothes does not come out smelling nice at all.

Or in my locale, a long dry pollen season that's murder on my sinuses. :(

Or a long, cold winter season where the clothes won't dry and may well freeze =(
