I might try that Rooster. One of my big regrets in the fossil collecting world is when I was in my early 20s I worked a pipeline job on the Montana-North Dakota border, outside the town of Wibaux, Mt., and the ditching crew cut right through a patch of petrified trees from the dinosaur (Jurassic) period.
I set aside a big chunk that weighed about 50 pounds, that had brilliant reds and greens and yellows running through it. I had planned to cut and polish that, but ended up leaving it out in a garden of a woman's home when a relationship ended.
You got off lucky.
