Barely a small town: the Rio Grande, a cemetery, some rocks -- plus an actual high-end resort with dining, shopping, an international airport of sorts, and golf. Mexico adjacent. It's the last stop of the fabled road to Presidio.
Where Mother Nature goes to get outta town: pre-primitive, canyons, mountains, deserts, lava-flows, fossils, wildlife, the Rio Grande, and an actual Pterodactyl. The Big Bend National Park & the Big Bend Ranch State Park are side by side along the Rio Grande.
Not even a small town: just mountains, desert, scattered ruins, wacky homesites, a Ghost Town, outdoor recreation, a bank, a few places to eat, some motel type joints, a gas station, and that International Chili Cookoff thing.
Bigger small town: courthouse, galleries, motels, restaurants, stores, vistas, civic buildings, Victorian homes, the Chinati Foundation, the railroad, excellent grazing, an NPR radio station, a liquor store, and the Marfa Lights.
Bigger small town: galleries, shopping, a historic hotel, civic buildings, a university, churches, parades, restaurants, rodeos, a downtown mountain, athletic fields, saloons, an Amtrak station, and an actual traffic light (blinking only).
The essential small town: downtown mountains & cliffs, a real cavalry fort, the actual Overland Trail, a historic hotel, the McDonald Observatory, dirt roads, assorted tall tales, and a drug store counter that still serves Sarssaparilla.
