I confess.  I really dislike double wide strollers. 

They clog any aisle or sidewalk they enter.  They are a product built for the convenience of a few at a cost to us all.  So I was very pleased to see this sign on the door at one of the exhibits at the Huntington Library:

Note to the Huntington: It is a risk to offend the inconsiderate.  Good Luck.

Note to self:  Maybe someone could invent a stroller that is a “Double Decker”
