One of the post in todays Solo/Group poll started by db posed an interesting question.
It was mentioned about fishing in front of a occupied campsite or trolling by, interrupting others solitude or shore fishing.
I doubt any one here would deliberately anchor off of an occupied site ( at least not that they would admit too)

But, I've inadvertently rounded a corner and right into a occupied campsite. This mostly has occurred when the weather is bad, and I'm riding the shoreline. I try to be a quite as possible on the water or in the canoe.
IF I hear noise up ahead, I'll try and move out from shore if possible, but if not, I cough or wave and let them know I'm coming by. I cough to give any Au naturel paddlers a chance to cover up or break it up

Depending on the looks I get, I'll either nod and keep paddling, or stop and chat for a few minutes. Most of the time being a solo paddler I've found others, especially in groups wanting to ask questions as they "think" I must know what they hell I'm doing

I've only had one group give me the EVIL eye, most are very friendly, asking about fishing/where from/where you going/how long you in for?
Some have even invited me for dinner/coffee

So what do you guys think? Avoid others at ALL costs? Apologize profusely BEFORE you can gauge their mood? Or play it by ear, and respond accordingly?
