Here's a suggestion.... carry a couple of golf balls with ya.... If you can hit them with one they are to close....keep in mind the occasional drifter is going to happen and if they move on just let them be.... This idea really works on wetbikers while trolling....keep in mind that you really need to lead the bikers....just some pointers here..... laugh
