Get familiar with the area
Always a step ahead of time, waiting for the occurrances.
2 camera bodies with many batteries, cards.
Besides those compulsory shootings, predict the possible motional moments. Be there, catch it.
Don't look back if you miss one moment, look foward, 'cause you don't have time.
Make a list, stack in your pocket.
Take any minute possible resting yourself.
Good Luck!
