Its the owners perogative to post his land, most dont as they may lose their right to protection under the NH recreation liability statute, and lose the 10% discount on property taxes given to current use owners who do not post their land. I am not a lawyer but section 3 of the statute copied below may be a good reason for the owner to post the bridge. Note, I do not see where posting the land takes away protection under the statute, but I have heard this multiple times at various meetings I have attended.
Alternatively, the owner may be worrried about "squatters rights" where allowing the public to use the path through the property may eventually establish a public right.
Pure speculation on my part is that the area gets abused during the summer as people assume its WMNF land.
