My paper has always been delivered at 4:00 am plus or minus 10 minutes.
With it being printed in Los Angeles it's not being delivered until later than 7:30 am.
I used to be a carrier for the Union-Tribune. Not as a youth paperboy, but as a adult I delivered the paper.
The papers would be delivered to our distribution center in the middle of the night. The trucks delivered the papers from the printing center in Mission Valley.
Now that they will be printed in L.A. and trucked down every morning, I would expect delays in delivery due to traffic, bad weather days, much more frequently than you have experienced in the past.
Perhaps this is a sound business decision on some level, but, having to depend on long distance deliveries each and every day could easily cause delays in delivery to the customer.
