Creative lobbying uses the principle 'Show Don't Tell", making your issue hard to ignore.
An Example:  Daycare Center Sit in
In 1989, low income working moms at a public housing project in Rhode Island pressured a public housing official for the daycare center they needed by turning his office into a child care center.  They brought their kids. They brought their toys, books, art supplies and even a diaper change table.
They stayed for the whole day, and invited the press. Eventually the official caved, and a permanent daycare center was set up in their housing project.
