I returned to Rockaway Blvd. this evening (site of a previous shark attack). New spam had sprouted, which I quickly uprooted. The worst offender was a furniture store that plastered its litter along a stretch of road under construction. There was no place to park, so I had to drive around until I found a spot (about 1/4 mile away), walked back to where the signs were, fought through waist-high weeds, knocked them off their perches, then carried them back to the car.
