We drove from Las Cruces to Guadalupe Mountains National Park, knowing next to nothing about it. We didn't learn very much. When we arrived, we learned that there was a wildfire (called the Coyote fire) and most of the park was closed. The area right around the visitor center and several nearby trails were open but that was it.
There are two campgrounds, one for tents and one for RVs. The one for tents was rather nice, but we couldn't fit in it. In fact, we tried to drive through it and found it was a dead end street, and we had to turn the rig around in very little space, not fun. The one for RVs was available but it was basically some spaces lined off at the end of the parking lot (with a nice view, though), so we decided to just go on to Carlsbad Caverns National Park.
Retirement is great. We bought a travel trailer and are exploring National Parks. (Actually, we bought one and sold it and bought a second one better suited to us. It happens...) And I have time to do some woodworking projects and things around the house. And now I have gotten interested in ham radio so there goes any free time.
