If it is your first year trolling - not sure opening day is best time to go.
Much depends on the weather - if it's nice , expect very big crowds. If bad - still will be crowded.
IMHO - if you get to ramp around 5:00 , you should be OK. Even if a few boats in line - gives you time to get rods racked , antennas up , etc , plus double check everything.
Often overlooked is Sunday afternoon. I know a few guys who leave about 3 pm on Sunday. The crowds thin out as day wears on and they normally get a limit before dark.
Opening day Saturday in Annapolis / Chesapeake Beach area has to be seen to be believed. I've done it 3 times - never again.
What could be more mundane than dying of old age or of natural causes when there is death by misadventure to be pursued ? Skip
