Know how much of a pain it can be when lanes have to merge together on the highway? There isn’t really any guidance how to do it; there’ll just be a sign saying right lane or left lane closed ahead. Most people see the sign, anticipate the merge, and move over when they get the chance. Some people will take the opposite approach and drive all the way to the front to the last merge opportunity and merge from there. These two merge methods are in direct conflict with each other, every person choosing to drive to the front of the line makes those in line wait even longer, so tension often results. Seems like there should be a better way… ….and on this trip, we actually have seen two. Up around Bar Harbor, the sign didn’t say left lane closed or right lane closed, it said “Lanes merge. Please alternate.” That worked great. Everyone drove to the merge point then alternated. Later in the trip, driving across New Hampshire, Vermont, and New York, we ran across a sign that said “Left lane closed ahead. Please merge early.” It worked great. Everyone anticipated and moved over early. No-one drove all the way up past the line to gain an advantage. It is so easy when everyone has the same expectations. Stopped at Alamo KOA in San Antonio. We’ll be here for a few days getting some work done. https://maps.google.com/maps/ms?msid=201563872774147443355.0004e02f0c80f1461c0bf&msa=0&ll=38.719805,-84.199219&spn=11.563316,26.784668
