No. You cannot bait on public land unless you have written permission from the land owner, in this case, the agency that owns the public land. Each parcel of public land is controled by an organization or department, and you must have permission from them, and you must file that permission along with a topo map to where the bait site is with the consevation officer who patrols the area. A lot of the land in the White Mountains is owned by the US Government. Ownership or control of other land in NH can be found on the

As to your question of selling skins, you can read the RSA controling that issue below, but in short, you have to contact the conservation officer in the area, have him seal the skins, even on coyote, before you can sell them. You can keep them for yourself, but under the law, if you are going to sell or give them away, they must be sealed (tagged)by a CO. Read the last paragraph carefully. I have had the Fish and Game make me give the skinned carcus of coyotes to them in the past. If you skin in the field, make sure you can remember where you did the skinning and make sure you didn't leave the carcus somewhere where someone might find it as the CO will probably get upset with you if you leave on laying by a trail somewhere.
