CAMPTON, N.H. (AP) — Families of New Hampshire fourth graders can get a free Christmas tree this year, if they're willing to work for it.

The White Mountain National Forest sells permits for cut-your-own trees for $5, but it's waiving the fee for fourth-graders who are participating in the "Every Kid in a Park" program.

Those who obtain permits are allowed to cut trees on National Forest land using hand tools. Some areas area off limits, and there are size restrictions.

Officials say several types of evergreens grow in the forest, including balsam fir and spruce, but participants should be prepared to do some searching.

Permits are available starting Saturday at offices in Campton, Lincoln, Gorham and Conway.
