  • June 2026
    This location is not a USPS. Per the guy behind the counter at the Sinclair gas station/casino their contract is cancelled.
  • January 2026
    This is no longer a gas station that accepts USPS items.
  • December 2025
    This post office has not been there in about a year, and is likely to not be there ever again.
