For me it pretty much boils down to 1. Whoever got there first has "rights" to the spot 2. When in doubt, use the Golden Rule 3. When still in doubt, go fish somewhere elseIt's sometimes difficult to know how to apply the golden rule if you don't know the intentions of the other guy. Which means a large amount of the time I end up just leaving and coming back later.I'd really prefer to fish a spot by myself being able to line up casts without distraction anyway.
