San Diego, Texas
Skip as a base: this is a 1–2 hour stop on TX-44 between Alice and Laredo, not a destination. Come for the county-seat square and Tex-Mex, then drive on.
San Diego is a small South Texas town of about 4,500 people in Duval County, on TX-44 roughly 8 miles west of Alice and on TX-359 toward Laredo. There is no hotel strip, no airport and no beach — the name is a coincidence with the California city. It works as a leg-stretch, a meal and a look at a South Texas courthouse square on the drive between Corpus Christi, Alice and Laredo. Plan an hour or two, not a night, unless you have family or business here.

Etiquette, safety and scams
Etiquette
- Greeting: Handshake and 'hi, how are you?' — reply 'good, thanks'; avoid: Treating the question as a real health enquiry
- Restaurants: Tip 18–22% and wait for the check; avoid: Leaving without tipping
- Personal space: Keep an arm's length in queues; avoid: Standing close to strangers
- Politics and religion: Listen more than you speak; avoid: Opening with hot-button topics
- Smoking: Smoke only in marked areas; avoid: Smoking near doors or in parks where banned
Scams and watch-outs
- Summer heat: 35 °C+ afternoons; carry water and do not walk far mid-day.
- Long empty highway stretches — fuel up in Alice or Laredo, not in between.
- US-59/TX-359 and TX-44 carry truck traffic; watch for wide loads and passing on two-lane sections.
- If you cross to Mexico at Laredo, carry your passport and check current border wait times.
Small-town Texas is generally low-crime, but this is remote ranch country: the real risks are heat, long empty roads and wildlife at dusk. Keep water, fuel and phone charge topped up, and lock your car at highway stops.
