I have fished Deep River for years.I try to Arrive at times when the lines arent bad.(early or late) stay longer than most.just to avoid the headaches at the launch.
I have seen the guy that runs the launch,make people pull out and go to the end of the line for jumping in.Because somebody wasnt ready.That 5 minute wait while the ramp is empty could be a lot longer if you jump in.
Dont necessarily like the protocal,but at some ramps its better to just adapt.
