In the PNW, mowing your lawn is a serious logistics problem because mowing wet grass is a titanic pain in the ass, and the grass is pretty much wet for half of the year. I'm kinda surprised there's as much grass as we have.

Most other yardwork activities can be done in the damp, or even in the rain (hello REI/Patagonia). Gardeners will tell you never to dig in wet soil, but the clay content in coastal soils is so low in many areas that it's a non-issue.
