Take on Old Exit numbers

Drive through Pennsylvania and every exit has two exit numbers. The normal one that every map, GPS or any person under the age of 70 recognizes and then beneath it, you get the "old exit" number. The new exit number corresponds with the mike marker which makes it really simple while the old exit number probably was used during the horse and buggy days. So today we get both. Like Exit 289 on Route 80 is also Old Exit 67 or whatever This is insanity, it's not that complicate and it is not as if these new exit numbers came about last year, they've had them for decades and nobody has the guts to pull the bandaid off and get rid of these atrocities.
Time to live in the now people.
