The rally is what the guys just stated, cruising, having fun, meeting great people with the same interest, hanging out on the various sandbars, having a few beverages, stopping at marinas/restaurants for food etc.
Fishing is up to each individual. I started a rally tourny a few years ago but not sure if ever happened last year or not. I get up every morning before the butt crack of dawn and fish til about 10:00AM then come back and pick up the wife then hang with the gang for the day. I do sneak away at times during the day and go searching for bass or early evening with Ben for stripers
