(Pawtucket, RI) -- The centerpiece of a small park at Main and Broad streets in Pawtucket is no more. The chalkboard wall with the heading "In my lifetime I want to ..." was meant for people to fill in the blank with something inspirational. But it turned into crude comments and pictures in recent months, and became a burden for the city to keep things clean. The chalkboard is gone and it is now an off-white color.
