A walk in Bangor tomorrow will help make dreams come true for some local children.The Walk for Wishes raises money for the Make-A-Wish Foundation of Maine. That group pays for trips and adventures for children with life-threatening medical conditions. For some kids that’s a vacation to Disney World or Hawaii – or even something more personalized, like an adaptive pool, right in their own backyard. It costs about $6,000 to grant a wish. And organizers say they can change the lives of the children who receive them.Dr. Colette Sabbagh, a member of the foundation board says, “They have life-long memories and it’s such a positive, wonderful thing for them. And they really appreciate it. Every single wish family I’ve spoken with, be it coming to the walk or coming to a Make-A-Wish event, they’re so grateful, so thankful, always willing to do what they can to help make a wish for someone else after they’ve received one.”Since 1992, the local Make-A-Wish chapter has granted more than 900 wishes – that’s more than a wish a week. The Walk For Wishes steps off at 10:30 Saturday morning at Paul Bunyan Park on Main Street. Registration starts at 10 a.m. For more information about other Wish Walks in Maine, go to www.mainewish.org.
