On our lake there isn't a lot of crappie or crappie fishermen and I think I am the only one that spider rigs, or at least that I have ever seen, I don't have any fisherman getting to close, the problem I have run into is pleasure boaters that see a boat with 6 long rods hanging off the front of it and they have to get a closer look, they may not be 20 feet( or closer) but they get very close under power and on plane. This doesn't happen all day but will happen several times each time I have time to go. This year I have started jig fishing more.
