So, here's the new zoo vehicle policy, instituted after an uproar about the previous new policy which banned driving on the zoo paths after 10 am, which means you can't haul or deliver anything.
When unavoidable with work or special requirements, vehicles can be driven in the park after 10 am with these conditions: slow and careful driving with an escort (person walking in front of the vehicle).
The escort must have a bright colored vest and mild noisemaker/bell...
At first I didn't see what was the problem with this policy. But then I realized that they would probably fire me for swinging the bell and calling "Bring out your dead...."
