I go out with my kids but they are respectful of other people and avoid the fishingpeople/lines etc. Not saying I've never done it but at least I make it look like I'm fishing, have bait, watch the hook etc. Heck even at night I put a glowstick on the pole in case I get a bite!
I get annoyed when its obvious, like a clown car at a circus and set up a full bar of glass liquor bottles etc, have half a dozen trucks w/1 pole etc.
You can fish, hang out, have a good time, party and not be obnoxious, party on the dunes etc. Only time will tell how much of an effect this will have. I'm really looking forward to 4th of July weekend!
