I remember going to look for petrified palm wood near Madisonville when I was in college. I didn't find any that I remember, but John Henry Faulk stopped and helped me pull my VW out of the ditch. :-) Madisonville is a nice drive from Houston. Here's a link I found from someone else's expedition near Madisonville. HTH: http://manly.delconet.com/klahn/mville.html Best regards, Bob
