Some things are different in the east... bridge heights, mayo brand names & TV/Radio station call signs are a few that come to mind...
I wasn't sure where the line is for the mayonnaise name is but in Washington state, Oregon, California and Hawaii the stores carry Best Foods Mayonnaise. In Iowa we have Hellmann's.
All right, I looked it up ....they change the name east or west of the Rockies. That was a hold over from when Best Foods bought the Hellmann's brand in 1932.
We are still in the land of radio & TV stations starting with the letter "K", I believe that line is the Mississippi river.
(Well roughly the Mississippi river, where we lived in Minnesota we were east, then south and finally west of the Mississippi river.)
Back at the Home Depot warehouse if they were sending a truck to the east they had to make sure it was shorter in height than a truck for the west coast. The word was the overpasses back east were not as tall as the ones out west.
What brings all this on you wonder? I saw something today in a parking lot that brought on thoughts of 'what's different here'. It was something that I was very familiar with from my 13 year vacation in the upper mid-west.
It was nothing I wanted to deal with again but I did take a picture...
