Dad, dad, dad. I have told you how to make room for yourself in the river. You pull out "sweet lips" (357) and hold it high in the air and empty it. Then reload and give anyone that is still standing nearby the evil eye and start fishing again. This will give you atleast 20-30 mins of hassle free fishing before the law shows up. You and Mike could take turn about doing this every weekend.
BTW. If you want to go with me to fish Slick Rock Creek I'm sure we won't have any competion from humans but, bring that pistol with you and I'll work on the otter population. We might even get to SEE a fish swimming if we're lucky.
