So I'm still working on my trailer backup but getting so I'm *almost* not embarassed. Anyway I looked up this thread after lining up in the water to get out, at Bluffers Park. When guys are both loading and unloading boats should you leave one side of the ramp open for each direction? I could have jumped into an opening on one side of the ramp but left it open (and boats behind me) to keep one 'lane' going both ways. So...be polite when it's busy both ways or catch as catch can?
