The Windsor Farm Trails here are mostly incorrect. They might have been redone since they were added to the map based on the 2022 update on this page: https://vitrails.org/portfolio/windsor-farm-trails/ I fixed the couple that I surveyed, but I'm sure all of the trails could use some work.

I believe some of the roads around the building should be listed as highway=service instead of track as they provide primary access to the driveway.

The building is also the site of the Buchmann Winery.
