In this real estate market, builders are having to taking it to the streets to sell condos in downtown San Jose. Downtown workers may have noticed a troop of young, attractive, sign-wielding “protesters” marching up and down Santa Clara Street last Friday afternoon, chanting slogans like “Less Dues, Better Views” while handing out superhero-adorned pamphlets. This intrusive if creative bit of urban guerrilla marketing was paid for by Barry Swenson, whose company is trying the get the word out about its City Heights high-rise condo development at 175 W. St. James St.
