Hello and welcome to the forum!
This guide is very helpful for new nominators, even if they aren’t rural:
I see that you are from Bonney Lake, WA. If you are comfortable, we can help you find some eligible things in your neighborhood specifically if you share the location. However, if the place is completely residential, the only eligible things are often amenities like a community pool, athletic fields, small parks, or other shared spaces not on private single family residential property. Otherwise, I think there are a lot of eligible things in your city, since the historical society seems very active.
The historical markers are great way spots for example, so are most things listed by the city here.
