My post has unintentionally missed it's point. It's my fault entirely as it's not for the first time. I seems to have some kind of 'dyslexia of the paragraph' when taking part in forums. Always clear to me, but means ten different things to other people. My apologies.
I'm actually looking to travelling there in my own vehicle (a front wheel drive) and wanted to know best routes, expected conditions, etc, to determine if this was at all possible.
Again, my apologies for any confusion.
I've a feeling I'm not in Kansas anymore.
