We ran Memorial Day Parade. Mostly uphill. Wear on tires minimal.

We elected not to drag the trailer around. Good thing especially since it was uphill. Wheels slipped badly on one section.
We borrow a generator that runs the driver station. Make sure you can run the robot and you have reset the WPA key. Very Important......
Test before you go.
Check that you can give out candy. Don't assume.
