With no explanation, chose the best option from "A", "B", "C" or "D". find no more than that the Wagners were negligent in erecting the chain, which as Carter recognizes, precludes any recovery by the Doehrings because the decedent was no more than a trespasser. We concur in our reasoning in Carter and we find as a matter of law that the Wagners’ erection of the chain was neither willful nor wanton. Even if we were to assume arguendo that young Doehring were not a trespasser, but was an invitee, and therefore the standard upon which to base a holding against the Wagners would be simple negligence, we would have found, as a matter of law, that the action of Doehring in driving a motorcycle at a high speed, at night, without a helmet and without headlights, was clearly contributorily negligent.
