The building's definitely still there (and still says Gamble Mill, but I found news articles that verify its closure). Reverted in changeset/38514129.

I saw that you changed back from vinyl_siding to wood, reasoning that there is no tag. But OSM isn't always about fitting into the values that exist. If you look here: http://taginfo.openstreetmap.org/search?q=vinyl#values , you will find that there is someone out there who has used it. Wood is certainly inaccurate, and it would be better to leave it blank than mistaken. I would say keep it vinyl_siding, or perhaps plastic, and hope that it catches on.

I vaguely remember doing this, and I would say it's because JOSM popped it up as a 'warning'. Would you explain to me the issue with those tags? I can't say I fully understand why they wouldn't be appropriate, but defer to your judgment. I've removed the tags, but would like to know for the future.

Sorry about that. You're right, I got confused about the directions of the oneways. I've been cycling around, so I have been getting used to the left-side driving. Thanks for fixing this.

Sorry about that. That was simply a mistake, not intentional.

Sorry about that. I've broken one of the basic rules. I thought I had been through this roundabout, so I apologize for confusing it with another one. Thanks for checking my edits. I'll make sure to verify what I'm doing with on-the-ground survey.

Would this actually be a path? Usually footway is used for sidewalks (paved). Also, notice the path that this parallels. Maybe those should be a single way.

Fair point. Editing may have been a better term. While nothing was seriously broken (routing issues, for instance), there were a lot of topological inconsistencies, so I made some changes to that. I apologize for deleting and redrawing the museum. I did not think about the history of changesets that would be removed. I will consider that in future.

My apologies. I should have phrased the changeset comment differently. I also apologize for entering your mapping territory. I understand your comments, and I didn't think about the issues for routing it would create.

I have reverted the deletion of the Pride Hill way. If there are other issues, let me know.

Wasn't there a big old discussion about half a year back about how the parade route SHOULD NOT be a separate way? It is not a separate path, and should not be mapped as one. DON'T TAG FOR THE RENDERER. The parade route should be if anything a route multi.
