Alan askew.........."I have recently discovered that apparently you can't
buy creosote anymore..............Any suggestions on how I could save the
fence or is it 'rip it up & start again' ?..."

Why creosote?
Not good for plants or people.
There are many other wood preservatives on the market as good as if not
better.
