I got a AAA map of Colorado because I know it has the Continental Divide Trail marked on it.  I thought it had the Colorado Trail, too, but it's not on there.  I noticed that it now shows another trail system - The Old Spanish National Historic Trail or something like that.  I did an internet search and read that there is now a series of national historic trails being developed.  I'm not sure which ones are completed, if any. I also don't have any real information on the use of the trails.  Does anyone know anything about these trails.  The Old Spanish National Historic Trail is really attractive to me, but I do see that at a minimum it is unfinished.

Thanks.  I'll look into it.
