After further checking, every one of the trails you've added within the conservation area boundary is in my notes as either "needs on-the-ground investigation" or "investigated, found absent". Is this the result of an actual survey, or just Strava?

At least two of the paths you added exist only in Strava, not on the ground, and the two footways you changed from "abandoned" to "active" are very much abandoned, and in places are no longer visible.

Could you slow down and be more careful with your additions? They've generally been quite accurate, but you've made a few major mistakes, such as way/1041264271 (a garden mapped as a building) or way/1041262862 (a building drawn over both a garage and a parked vehicle).

I've only verified the southernmost 500 feet or so -- I was coming back from a hike to Upper Blossom Lake, and noticed an information sign on the other side of the road (which I appear to have forgotten to map).

Are you sure the State Line Motor Trail is a "highway=track"? The Thompson Pass end was very path-like when I surveyed it four years ago -- I'm sure I couldn't use anything with more than two wheels on it.

In case you haven't noticed, the United States isn't part of Europe, Africa, or Canada.

There's no need to put three names into the "name" field -- one is sufficient. That's the whole reason there are "name:lang" tags.

Welcome to OSM, and thanks for adding some missing businesses.

Please be careful when editing. You did two of what we call "node drags", where you accidentally pull part of an object across the map. I've fixed them, but it's something to watch out for in the future.

As far as I know, all the major consumers of the "piste:grooming" tag understand the "classic+skating" notation. As far as I know, none of them understand separate tags. This strikes me as a case of "if it ain't broken, don't fix it".

That's a *former* golf course. It shut down years ago, and there are currently plans to convert the land into a residential development.

I've added the full-length name to the "official name" field. That way, the building can still be found when searching by the full name, and anyone making a custom map has the option of showing it.

Is there a short name for the building that's in common use? "John and Joan Bollier Family Center for Integrated Science and Engineering" is rather unwieldy.

The data source you're using is outdated: you added Spokane County Station 48 in its old location, but the station moved a mile and a half to the southwest five years ago.

(The old location is mapped as a "disused:amenity=fire_station".)

"Currency exchange" is meant for more mainstream currencies, such as Euros or Yen -- things you could spend at a typical store.

I'm not familiar with the business, but from the signs visible in Bing Streetside, it looks like "Red Line Coins" is more like a "collectibles shop" than a "currency exchange".

I already fixed the multiple-coverage outlines ones I saw. The clearest example would probably be way/1005616535#map=19/46.41575/-117.04922 where the outline originally covered the two buildings to the north. If you use Esri Clarity imagery or view things from the side using Bing Streetside imagery, it's clear that it's two houses and a detached garage.

If you want to see the changes I made, it's changeset/114160231 (OSMCha lets you view the changes in the context of imagery at https://osmcha.org/changesets/114160231/).

You turned Okanogan County into a river. I've fixed it, but please be more careful in the future.

Could you please be more careful in your checking? You had two buildings overlapping driveways, and about three dozen cases of a building outline covering more than one building.

The upper trail network was completely re-worked in the past year, so some of the Strava heatmap tracks are stale (I think Strava uses a three-year history).

When I was surveying the area a month ago, I ran out of daylight before being able to check more than the junction between the Quinnamose-Saltese segment and the California Creek and Moonshine trails, but I think your routing is mostly accurate. However, when you deleted the stub trail I'd added, you discarded the surface information and access restrictions (and I think the access restrictions are different for the Mica Peak and Liberty Lake segments).

The small trail segment you added near the west end of the Quinnamose-Saltese segment (way/1005076838) was heavily overgrown with brush, and I suspect one of the tracks you extended (way/432963144) is similar.

I think this needs to be reverted. At least one of the Mica Peak trails you added doesn't exist, and I've got my doubts about a second one.
