A Fond du Lac county farm safety specialist says a new ag tourism liability bill seems to make common sense. The bill took effect April 18th and adds ag tourism activities to the types of recreational activities that qualify for immunity from liability. Extension farm safety specialist Mike Rankin says ag tourism is becoming big in Wisconsin. Rankin says the law doesn’t absolve farmers of taking responsibility. "...you wouldn't invite a group of 3rd graders out to the farm and suggest they crawl up the outside of the silo to get a better view," Rankin said. The new act requires that signs are posted relating to the inherent risks on a farm.
