The Milford Daily News HOLLISTON – Gail Marro's family settled in Holliston because it was a small, rural town, she said. Last week, Marro and her husband began picketing outside Holliston Town Hall to keep it that way. On Thursday, more than a dozen others, hoisting yellow "Stop555" signs, joined them. If you Google that phrase, you'll likely wind up at stop555hoppingbrook.com, which was launched by concerned residents like Marro to enlighten the public of a massive project being proposed at 555 Hopping Brook Rd. in Holliston. The project's developer, St. Louis-based CRG Integrated Real Estate Solutions, is planning to build an 800,000-square-foot warehouse at the site located in the Hopping Brook Business District, abutting the Medway line.
