I live on the Sacramento area and the closest water to me are the multiple rivers that run through my city. Is driving a flat bottom v drive on the river a no no? The reason I ask this is because I have never even driven a v drive and these things don't have reverse. Should I learn and get comfortable on the lake first? I don't want to get on the river and not know how to get out without wrecking my boat into the side. Thanks in advance.
