"the tribal claim is that a launch will add to marine traffic and create unsafe marine conditions, and therefore hamper their ability to harvest their half"

They of course don't truly believe that themselves but are throwing up any argument they think may stick. When we rule in their favor on such a ridiculous argument it only sets bad precedent and encourages the craziness.

What do you think the true reason is they don't want it? Spite? They want the Sound all to themselves? (that ship has sailed and never coming back to port).

Heck, pay them $1,000/lb for the 12 crab a year they may not catch because of the launch as mitigation.

Crazy Town!
