Thought we had seen the last of Gary Rosen’s beloved rubber sidewalks? Think again. Rosen CCed us this week on an email he sent to Dan Joyce, a representative from RubberSidewalks.com. Rosen wrote that “I also look forward to continuing our discussions on whether Worcester… should join Boston and Cambridge…in looking into the feasibility and affordability of rubber sidewalks.” And, of course, Rosen couldn’t resist a barb in our direction. “I sent the topic of rubber sidewalks by the Worcester City Council about a year ago. Unfortunately, it wasn’t taken very seriously by many of my colleagues in elected and appointed positions. My good friend and Worcester Magazine reporter, Scott Zobeck[sic], found it quite amusing and has given me some good-natured digs. However, his skepticism on this issue is shared by many in our city. So I do look forward to continuing my and their education.”
