I-5 North and South, pedestrian bridge south of Rosa Parks Way. Gap between handrail and fencing makes for a perfect cage for cardboard signs. Posting takes less than a second: like dropping toast into a toaster.
Alley next to the 2800 block of NE Sandy. A fine overlook of I-84 East.
Same fence 200 feet to the west. This gets the westbound traffic.
In front of the Fred Meyer on SW Barbur.
Water Ave. under the Hawthorne Bridge, just past the homeless encampment.
Bike path between E. Roy St. and Bellevue Place. Incredible head-on exposure to I-5 north and south. Borrow the pallet from the nearby homeless camp to deal with the thorns.
Guardrail behind the island at 43rd St. and 5th Ave. NE. Great exposure to I-5 North and South.
Cel tower fencing at Park and Ride lot on 5th Ave. NE, just north of
130th/Roosevelt Way exit on the 5. Steps away from quiet, easy parking... good exposure to northbound 5.
