The Luckenbach post office has been shut down for a long time, it’s only there for show. From the History of Luckenbach, in the words of Hondo Crouch:
“Four weeks after we’d bought Luckenbach store the joke was on us. We found out the government was closing the post office. Thirty-seven families still had boxes at the post office. Although there was a sharp decline in grocery sales, beer joint patrons & egg customers remained loyal. Even though Hondo wrote a futile plea to Senator Tower, he made a joke out of losing the post office. “I’m so conservative. Its my fault,” he told the people. “But I just couldn’t see why I should send a big mail sack with one little letter down in the bottom so lonesome. I kept it ‘til I got it full. Took seven Months.”
Hondo was a good Republican, so perhaps they were basing their post office closing decisions on politics back then, too!
HEHEHEHEHE! You can still buy stamps and mail your letter from there though.
