Rick, I agree with John Cole. ALL narrow gauge is interesting. And we learn of sites other than Colorado when folks like yourself post links to those sites.
I don't believe the supporters of this site meant it to be narrowly defined (no pun intended) to Colorado. Colorado seems to be "Mecca" for NG folks. But, there are a lot more NG lines and info out there. Personally I like to hear about it all, and hope someday I can visit some of the other lines.
Give us some links so we can learn more about NERAIL. In the mean time, I will do a Google search for it.
