Talk:US Migration Trails and Roads

This chart is very helpful, but it is static. It shows the date each early trail or road began. However, a video for each trail or road showing the growth/length by five years or even by decade increments and the counties (preferably as they were on that date but I'd be glad to see even current county boundaries) around at that time would be invaluable to researchers tracing their family trees in the late 1700s and early 1800s in the U.S.
