Please do your stuff in smaller areas at a time. It makes it easier to find mistakes, such as how you moved a fire hydrant in Los Altos, California, into the middle of the street.

Please also be more descriptive with your changeset comments. I'm assuming that moving the fire hydrant was a mistake, because fire hydrants in the United States are not normally found in the middle of the street. A better comment (eg. "Improved building alignment") would make it clear that moving the fire hydrant was unintended.

When you're editing a roundabout, make sure you don't connect an entrance road directly to an exit road. That creates a "short circuit" and causes routing software to give incorrect instructions.

For example, with the "4th Avenue" entrance connected directly to the "West Marie Street" exit, a router will ignore the roundabout entirely; the curve is gentle enough that it might not give any instructions at all. With the two separated, it will give instructions such as "take the first exit from the roundabout".

I've deleted Creedonia.

Don't add fictional things to the map -- it's a good way to get yourself blocked. If you want to create a fictional country, OpenGeoFiction.net is a project that lets you do so.

About a third of the buildings you added had "building=yes" on their nodes as well as on the way. I've fixed it, but you might want to re-evaluate whatever your workflow is to keep it from happening in the future.

I've reduced many of the trails to T1 or T2 based on my (sometimes rather hazy) memory. I've left Paintbrush Canyon at T3 because I've never hiked it, and in the aerial imagery, parts of the upper reaches look like they might be a bit tricky.

Zero lanes on the freeway off-ramp? That doesn't seem correct to me.

The place was named by French fur traders in the 1700s -- you can probably find at least as many French spellings as there were traders.

"Dock" is for drydocks and similar ship-repair facilities. The tag you're looking for is "Pier", and the editor won't let you put it on points, only on lines and areas.

As far as I can tell, the original city line was correct: the Spokane city limits run down the west side of Havana, the Spokane Valley city limits run down the east side, and Havana itself is in the county.

You might want to work on your aim. A number of the crossings you've added recently have been close to, but not actually on, the point where a pedestrian way intersects the road.

When you're editing in Spokane County, Esri World Imagery is far sharper and better-aligned than the other options, and is nearly as new as Bing or DigitalGlobe Standard.

Where are you getting the route of this railroad from? I'm not seeing evidence of it in the aerial imagery, and neither the 1903, 1961, nor 1987 USGS topo maps of the area show it.

Where are you getting the name "3I" from? Looking at historic topo maps, it appears to be "state highway 31", and I can't find a reference to it that's less than 68 years old.

Where are you getting that this has a traffic signal? It was a four-way stop when I drove through a few weeks ago, and I haven't heard of any construction since.

Where are you getting the street layout of Tecomate from? It doesn't show up on any of the aerial imagery.

Don't vandalize the map.

Please stop making changes based on outdated maps. Inland Empire south of 23rd hasn't been an arterial since it was cut off from US-195.

Maxwell between Washington and Ash was re-engineered earlier this year in a way that's significantly reducing the traffic flow.

Are you sure this is a state park? The Flathead County Parks website lists it as a county park: https://flathead.mt.gov/parks_rec/parks.php

The "Salmon River" relation you created has a waterway type of "LowerSalmon", which isn't a valid type, it includes a seemingly arbitrary part of the Snake River, and it excludes a similarly-arbitrary part of the Salmon River.
