Seriously if the water got high enough that stuff would just wash out. We are going to have a huge water year. Predictions say higher than anything in the past 40 years, so i understand why the neighbors freaked. Honestly the neighbors should have just walked over and talked to you about it though. Then you could have explained.
My other point is Proof. As far as I remember that row of rocks has always been there. So what if you were out moving rocks looking for crawdaddys. If anyone else ever gets caught I say prove it! Though the black opts with nightvision goggles sounds like the best idea!!
Seems to me that if they wanted someone to take it down now, they would need a permit
to change the river, so enjoy your new wave!
