If you bring children to the race please have control of them. Hyperactive eight year olds running back and forth across the field is not a good thing.
If you have "professional" glue your tubular tires, before the race check that they are actually glued...
Murphys law: If you survive a somewhat sketchy field, you can get almost taken out by some idiot not stopping for stop sign on your cool down ride.
That is all.
