Depending on where your staying ,there are numerous ramps on the LBL side.You can trailer across the 68 bridge and put in at one of the ramp's on that side(sugar bay for one I know has a ramp). That would be the wiser thing to do, Sometimes the wave's can get very large and you can't just go straight across, you might have to run a mile or 2 up or down the lake to work your way across, beside all the underwater hump's and ledges, you have to stay inside the buoy's are you could lose a lower unit. This lake can be very dangerous if your not familiar with it, and there are a few death's every couple of year's even with people who know the lake. Get you a map of the Lbl road's and should be fine.
