It was my first Kingston Open last year and I actually fished with John and I couldnt of been paired up with a classier guy. And I am looking forward to this year. Treated me like I was a friend right away. All the pros are great.
Like neil said alot of the guys wont take the gas money during the tournament, but if you are running all over the place during the tourny or prefishing with someone try and get them to take it.
As for food and drink I learned that all you really need if anything is just some water and maybe a few snacks because when your fishing time goes by way to fast and you barely have any time to drink and eat anyways.
Equipment- Best thing to do is to just talk with your pro and ask him how you will be fishing and what techniques will be prominent all day. But definatly depends on the boat also, I found that you only need a few rods anyways because the pros want u to use what they trust in and will give you all the gear you need, so limit ur tackle.
Launching and Loading- Refer to Johns
Garbage, etc...-Just clean up after yourself and use common sense, treat the pros boat like it was yours. After the day is over, help them out with anything they need done.
Once everything is wrapped up go for food and plenty of beer.
