Depend on location, I'm gonna fish at. I mostly bring one rod and reel and a back pack with a few bags of plastic and Plano box full with all the hooks/weights when bank fishing sometime two when I wanna try new technique / lure at that location. 

But at a few parks I can park my car right next to the fishing spot so I bring more rods and reels pre-tie with different kind of lure just in case.

I don't limit myself at all, never know what you might need. I bring a good bit of gear, most stays in the vehicle but it's there if I need it.

I learned to bass fish casting from the bank with 1 rod/reel and 1 lure a Hawiian Wiggler #3 weedless spoon adding a Creek Chub Injured minnow top water a few months later and caught lots of bass back in the mid '50's. Shore fishing limits where and how you can fish.

The 1 thing bass anglers have in common is buying more lures and tackle then we can ever use. How much stuff we carry is limited to to our ability to carry it.
