For $1 you can see the infamous "The Thing" which is advertised by about a million obnoxious signs along Interstate 10. If you really care, I will tell you about it for free. While there you can also pay an extra 20 to 30 cents a gallon for gas, buy overpriced souvenirs and eat at Dairy Queen. You cannot even see the remains of the Johnson Ghost Town because they are on private property. The best idea is to keep driving.
Fun Alternatives: Instead of the Johnson Ghost Town; try Fairbank, or Gammon's Gulch near Pomerene. Instead of paying a dollar to see "The Thing" try almost anything else.
