I'm not sure where Day's Inn is in Scottsboro. You need to get an "Atlantic" brand map of Guntersville Lake. Wal-Mart and most stores that carry fishing tackle will have them. They show the location of boat ramps on the lake. I suspect that the City Park or Jackson County Park ramps would be closest to you. They are free. Goose Pond Colony has a good facility, but they charge a small launch/parking fee.
The map will show you where the 3-9 feet of water areas are. (shaded in blue) Look for weeds on your depthfinder and keep moving until you find fish. This time of year, when you catch a fish, more are in the area. Slow down and work that area good. Good Luck!
