t-roy, the best place I found when trying to prepare for the upcoming spring fishing was in the forum reports from spring break last year. Good information on what was biting what days and what the weather, wind, water clarity, etc. were like on the days fish were being caught in good numbers. Here is the link to one of those pages. Hopes this helps and good luck with in-laws. I know that feeling all too well.. Have fun!
