I am lucky and fish with a buddy of mine that offers to let me up front sometimes, he tells me what he's leaving me to cast to, etc. In turn, if I see that he's throwing a crankbait or something fast moving, I throw something similar because we're covering water and I don't want to slow it down with a shakey head or something like that.
I do the same whenever I'm in my boat and have a backseater.
I have had some guys that don't give a rat's pitoot about the backseater.
