HOLA my amigo Springfield,
Thank you for remembering and asking - yes still making progress on it, now over eight years on one project. I had been feeling a bit embarrassed for taking SO long when a good fiction writer can crank out a novel in a week, but recently noticed that author Frederick Pohl took over
25 years writing "
Atlantic Crossings Before Columbus" which is a very similar work. Probably if I spent as much time on it as I do
blathering on Treasurenet, it would have been done years ago!
I did contribute part of a work with many 'Alternative History' theories several years ago, covering only Carthage in a short version. That bit is online free at Google Books, if you are interested I will send you the link.
One major difference that I see is that I cannot agree with either the Isolationist theory who state that the Americas were in utter isolation from the end of the Ice Age to at least the arrival of the Norse, or that of the Diffusionists, who claim that vast fleets of ancient mariners were criss-crossing the oceans on a constant basis, the evidence just doesn't support either camp. I am sure that folks in both camps will disagree with my ideas pretty strongly.
I hope you have a great evening amigo, thanks again!

your friend in 'Dakota Territory'
