How would you deal with this-Aggressiive Dogs & Owner on Run Route?

I wanted to know how everyone else would deal with a situation like this?
First, A little background on the subject....
I have been running the same route in my neighborhood since January, training for triathlons and marathons. My "neighborhood" is a very rural area in the country where houses are spread apart,and usually sit on many acres of land. This particular situation, The Aggressive dog owner has more than 100 acres,that has been in their family for a long time, Where several members have built homes on it,So it seems as if they own the entire 2 mile stretch of that road.

The problem. The dogs at this house would chase me and nip at me, Very aggressivly. The owner stoped me one day and told me the name of the most aggressive dog, Told me if I call him by name,Maybe ,MAYBE,He wouldn't bite me. Well, Day after day, I run, The dog nips,and I call him by name to tell him to stop. The dog seems to get more aggressive when I call his name.

I have been bitten in the past out here by other dogs while running.
I finally called the dog catcher and explained what was going on. He told me I should go and file charges on the owener.I didn't,However, The sherrif was sent out here,Took my statement and said I was in the right,He went to the owner and told them to restrain the dogs, or he would haul yhem off.

Ok, Dogs are no more a problem.
However, NOW it is the owner!
There was an accident involving a sherriff deputy in the dog owners yard,as I was running by and saw it, I stopped to see if I could be of assisttance. The dog owner began yelling at me, In front of the deputy, Telling me he was going to kick my BLEEP BLEEP! Using horrible language. He was jumping at me,and threatning me,and another man was "holding him back",Then he began yelling he was going to run me over with his car and kill me and be waiting for me at 5:30 am the next day(The time I normally run past there). I asked the deputy "did you hear that" He responded I don't want to hear all that arguing!!! I couldn;t believe it. This man is threatning to kill me, because he could not keep his dogs restrained,and the deputy tells me to leave,and dont come back around.

I forgot to mention before I called about the dogs, The owner would purposfully let them out on me, He has a doggy door that lets out into a fenced yard, But he would open the front door and turn them out on me.
I never done anything to the people,Before calling about his dogs. I wave at everyone, I never act like I own the road,I give the right of way to everyone.I try to be curteous always.
I am in no way afraid of this guy,But my wife insists I change my route to not aggravate the situation,What would you do?
