Is there any site that's keeping track of progress on the wall? It's hard to stay up to date, since most of the media is deliberately not reporting on any kind of border wall progress. It would be very useful to have an interactive graphic or map of the southern border divided into sections. Each section would be colored to indicate the currently known status of that area. Black could be "natural barrier already exists", red "no wall", yellow "wall in progress", green "wall built". Clicking on a section would bring up a list of links to sources (video footage, news articles, etc) verifying its status.
