Because a lot of it is food transport. A railcar can’t bump the receiving dock at Kroger.
If folks wanna slow down the China stuff coming into Savannah, they can do things like: quit thinking they need to update perfectly functional kitchens and bathrooms. A lot of home improvement costs are helping to build the wrong military.
I know some truckers that haul special baseball/softball diamond dirt almost 200 miles,..... to high schools!! Is that necessary? How many kids in the school play the game competitively? A tiny fraction.
Priorities, people, priorities.
Across the street where I work there's a middle school than had a baseball diamond built a year or so back. Intersting watching the construction while they built it. Brought in that "special diamond dirt" you mentioned. Beautiful set up when it was finished. What did the schoool then do? They abandoned it, and within months weeds had overgrown the field. Your liberal school tax dollars at work!
