My partner and I will be fishing the Fishers of Men Regional tournament on the Atachafalaya River basin out of Morgan City in late October. Are there any commercially available maps available for Humminbird or Lowrance GPS/Sonar units? I have looked at the area with google maps and feel that we will need all the help available to make it out alive! Finding some good places to fish would be great also.

What I am considering doing is getting a chip and using it for the week we are there then trying to sell it at a discounted rate since I will only need it that one trip. Any help on the best option for that area is greatly appreciated.
