You just need duct tape, gorilla glue, and JB weld!  That'll fix anything.

I'd replace the posts with steel pipe in concrete, it'll last you pretty near forever.
You just need to replace the in between every so often.

That is actually a pretty good idea Versy. I looked up some pictures though and not sure I really like the look. Especially since I did all of the back fence (the longest side) a couple of years ago in all wood. If I were doing the whole fence I think I probably would go with the steel posts.

our bikes don't do well in the wind

Being from down here in Hurricane central, I have replaced many a fence and often wondered why the fence companies use the "tie in" type metal between fence posts and make one big no seamed fence line.

So when I redid an 80 foot section between me and my neighbor to the north... I built one that is sectioned, 6 foot between centers of my ground posts.
I then cut umpteen billion pieces of 2" X 4" pieces of wood and made some "shelves" for the 2 X 4's that go from post to post. I then just set the fence boards about 1/4" to about 1/2" gaps between to adjust for the coverage between posts.
I only used 2 each 2 X 4's per section, 1 foot off the ground and 1 foot from the top of the fence... yeah they bow a little now and then, but still serve the purpose of a privacy fence and keep kids and animals out.
I then put 3 screws on each end fence board into the 4 X 4 posts, so that only six screws hold the fence sections up, but since they rest on my 2" X 4" shelves weight is no problem.
Now all I have to do when a Hurricane comes is to remove six screws per section, then lay them down in the yard and strap them together.
I could also put an anchor or two to hold down the whole lot if needed.
My initial idea was to put anchors along the side of my house and use the sections to protect my plastic siding and windows.... I still might do that.

Mmmm. Most interesting there Old Rider.

Hey Youzguyz, I said I would report back so here is the scoop. The rotted posts were set in concrete, so between that and huge roots next to the tree that has grown so much, the spacing of the posts had to be changed and was not consistent. Therefore I had to remove all the pickets from the old fence, removing each screw one by one (took a very long time). I replaced all the posts, and most of the six inch wide board at the bottom of the fence. I used only two new 2x4x8 and after  tearing up 3 phillips head bits and wasting all that time with those screws I switched to T5 star head screws and the pace really picked up. I have probably over 40 man hours now into the clean up, reclaiming of the wood and installation of the "new" fence but still have about one or two hours left before I finish. Working in the dark was just too difficult and I was tired and hungry anyway. Hopefully I will be finished with it tomorrow night. Cost of new materials not counting post hole digger and shovel was around $200.00.
