I liked the way there was an obstacle in the middle of the field last year (bridge + bar), that allowed different robots to overcome the obstacle diffently (some went under the bar, some just went over the bridge normally, some (well one
) were an extension to the bridge, etc.). Something to make it more interesting for the drivers might be to have columns in spots so you have to go around them, or have half the field blocked off except by one narrow ramp, or some other sort of devious obstacle that Dean is so good at creating
