Thanks guys, there are a ton of docks on Conroe, narrowing them down by any means is helpful. Identifying which are brushed is a good idea, I don’t have side scan but there may a correlation between brush and “fishing” lights.
These dock owners will also have some small ropes dropped over the side of the dock with brush tied to them.
The dock may have lots of Rod holders mounted to the rails.
You will usually see several rods and reels setting around as they come down often to drop a Minnow over the brush.
The brush is not always under the dock. The main pile may be right under your boat as you are working the dock. Keep an eye on the sonar at all times. The pile may be a cast distance away from the dock.
