I've managed to get mostly everything I need stuffed into a nice little Plano Guide Box. It's all waterproof and it floats, which is great when you accidentally dump it in the river.
I've got another little multi-compartment box that fits perfectly inside the bigger box. The smaller one holds a mess of smaller hooks, splitshot, slip sinkers and swivels, too.
As far as bobbers go, I like to keep a couple small ones hand for worm or leech rigs, and two bigger ones for live sucker rigs, both for when I am posted up on one of the local lakes.
I like to keep a variety of hooks on hand, 'cause you just never know, right. They range in size and style anywhere from a size 6 plain baitholder hook, for worms and shit, all the way up to 10/0 circle hooks for big 'ol slabs of cut suckers. For the most part I find myself using 1 - 2/0 circles hooks in the river for worms and smaller bait rigs. The bigger circle hooks I use on my heavier rigs topped off with big 'ol pieces of cut bait.The weights I keep in my tackle box also come in a broad range of shapes and sizes. Smaller 2-3 sized splitshot all the way up to 3 oz. baitcasting weights. Once again, keepin' a variety of sizes on hand makes it super easy to switch up from the river to the lake.
I've also recently added some lures to mix, the floating and shallow diving ones I find are the most versatile for both the river and lake, and are definately the most "weed-free" as far as the l lakes here in the cities are concerned.
I have also managed to cram in an extra pack or two of leaders, a hook sharpener, and the famous Zebco Fish De-Liar, which I guess never really put to any use. In addition to what I have stuffed in my tackle box, I carry a nice leatherman multitool, a small little headlamp(to free up the hands), a pocketknife, some spreaders, and a good flashlight,too.
