Earlier quoted context omitted.
Even a little before dotcoms, there was a perception in the Pacific Northwest, of Californians moving in and driving up prices, and there were the jokes: "It rains all the time! Always gray! And slugs everywhere ! We have to check inside our shoes before we put them on!"
Those aren’t jokes but all accurate warnings. E.g. the slugs: https://www.reddit.com/r/Seattle/comments/2fd5f3/banana_slug...
And when a slug sadly squishes underfoot (worst: between your toes), it's this weird slick adhesive that you can't wipe off, but has to be scrubbed off before the noticeable slickness is removed. Then you probably want to keep scrubbing, for grossness.
When visiting the coast, in the morning we woke to find multiple large slugs scattered around up the glass patio door window that faced the ocean. It was a mixed view.
