New Mexico, which is a screwed up state to begin with, has a problem with DST. With standard time, there is a time zone change with Texas. During DST, there is a time zone change with both Texas AND Arizona! So if you’re driving from Amarillo to say Flagstaff on I-40, you gain two hours going and lose two coming back. I don’t know what to call that - highway lag??
And highway LEAD going the other way??
