I've never fished Yo Yo's but often wondered with crappie being soft lipped how a crappie of any size at all wouldn't pull out before you got there?? I know if folks have got them set in a cove where your fishing you can really load your boat once they start going off if the owners aren't around. Course if you see them coming you've really gotta to get away! Really I'd never do that I just wanted to see what you guys would say. Sad thing is there are guys who would run others lines. I've had em run my trotlines and throw lines before.
