If all goes according to plan, today Seattle will join L.A., Dallas, Salem, Oregon, and about a dozen other U.S. cities where citizens have hit the streets by the thousands (and hundreds of thousands) to rally for fair immigration reform.

According to KING 5:

The march in begins at 3:30 p.m. Monday at 20th Avenue South and South Weller. Demonstrators will march up to Jackson Street, along 12th to South King, onto Fifth and South Jackson, then to Fourth, to Madison, and finally to the Federal Building on Second Avenue.

Organizers are expecting up to 20,000 marchers, and afternoon commuters are being warned to expect delays….
