Thanks for the wealth of information in the replies. I'm very familiar with the etiquette. Hell, for many of the folks we knew along the lake, we'd actually bring 'em fish the next day.
I may give it a shot on Big Lake one of these days soon. I'll be sure to post a report.
And when I wrote "their" lights in the original, I really meant "their" fish. Of course, the lights are theirs.
