Rice lake bass advice

[Kwan]

I am planning on hitting rice lake with my dad for bass. We're planning on using plastics, so what should I look for in the water? Deep weed lines? Shallow bays? We're probably going from Bewdley or Gores. Is it worth it to head farther up north? I've always been curious about that sunken railway. They say spots between the islands and the railway can hold smallys and wallys... We won't have a sonar working, though
