Bring a lot. You may not need them but nothing is worse than running out of bait when you are having the time of your life and this is the time of year for it. Three dozen a person ought to be enough. For bait and for chum. And don't scrimp on the dirt either, it comes in handy later.
Lets look at tackle.
Seven feet is about right. Besides, it helps on the hook set too. Rigging the bobber. It is important to weight the bobber properly so that you can detect bites that pull down AND bites that lift up the bait. Round bobbers can't tell you this but the pencil ones will.
