I'd expect most of the spectating action to take place right when the park opens, and then when folks land again -- probably between 2 and 2:30. I don't know that area, but folks generally don't cycle back and forth to the launch -- they launch, they go where they hope the fish are, they fish, they come back.
This is a catch-photo-release tourney, and so far, the photos pretty much are used for cases in which the Honor System breaks down. So there's no elaborate weigh-in like at the big bass tourneys.
The other place you might want to check out is back at the store at 3:00. You can hear all the stories about what went on that day. That's where the results are tallied and prizes awarded.
