When traveling on I 76 in eastern Colorado, the Roggen Country Store, exit 48. It is the Conoco station in the town of Roggen. They do not allow use of the restrooms for anyone, gas customer or not. The restroom doors are locked and there is a sign telling you to go to the rest area. The rest area is 18 miles east at exit 66A in Wiggins. And there are no other businesses in Roggen. The nearest gas station is at exit 39, Keenesburg. Go to Wiggins or Keenesburg. The bathrooms are clean and unlocked. And the gas station operators are much nicer!!!
