A couple of suggestions:
In years past, the local "Angel" tree has been sponsored by the South Walton Fire District...you select a child's name, and they give you the gender, age, and suggested gift list. The gifts are delivered unwrapped to the SWFD's administrative office on 393 north...and they wrap and deliver the gifts in time for Christmas. The donor's don't get to meet the children involved for privacy reasons.
I think the Sheriff's Office sponsors something for families in need. Call 892-8186, ask for Lt. Eddie Farris.
Also, Sharing and Caring (Neally Business Village on Hwy 98) is always glad for donations.
Bless you for wanting to help. Good luck!
