Tips to Catch Nesting/Bedding Bass
This is the best most complete article on catching bass off of beds that I have ever read.
If you ever read or hear someone say they can catch any largemouth they come across on a bed then they are BSing you.
Also an important point that I thin should be derived from this article is that people who catch big female bass sight fishing are just catching a female that happens to be in the area. The actual bed belongs to a male bass. A female may help in making nests, but they don't keep them or if they do keep them it isn't for very long at all.
