With the PC winterized and in storage, I am dreaming of the spring trip in April--once ski season is over. We are planning on heading south from Denver, through New Mexico, with goal destination of Big Bend National park. We want to do lots along the way. Have been to NM many times so have many good ideas, but would welcome unique suggestions. We have not been to that part of Texas, so am looking for input from any experienced travelers in that area and in the national and/or state park.
