I agree with most of the comments regarding trains, sites and condition of the place. I can tell you this is the only "park" I truly felt uncomfotable walking after dark in with my wife. So I wouldn't!! Better to pull off at a Walmart anyday!!!
Hard park to review. While the construction and property are excellent, the layout of the park especially the pull through's are similar to staying at a Wal-Mart parking lot. While that may sound harsh, we actually had a nice time in this area and if we were to travel again to the Sierra Vista area we would stay at the park. There is no age restriction.
