I have a question on drop shotting. Can it be done from shore or does it work better from a boat?
Sure, You can drop shot from shore. If you have a long cast just raise the height of the lure from the weight. I wouldn't just go fishing and say i'm going to drop shot. All techniques have a purpose and a time to use them. i use electronics to find suspended fish and drop shot to the desired depth and at times i use it to suspend a bait just above the weeds in a horizontal fashion.
Maybe Carolina rigging would work for your needs from shore?
You never know what the fish want and you need to try until you figure it out. I'm not a shore fisherman but i would absolutely drop shot from shore also because if you get hung up the weight is designed to cut away and you can still retrieve your lure.
