Back for an encore is the New Hampshire Association for the Blind's nonprofit challenge. Several nonprofits have already accepted the challenge to participate in the Blind Awareness walk-a-thon on June 5. While raising money to support programs for the blind, nonprofits raising a minimum of $1,000 will get half back to benefit their own organization. For more information, contact Mary Chase at firstname.lastname@example.org or 224-4039, ext. 324. Additional walk-a-thon information can be found at sightcenter.org.
