Their first contact was with Rufus, ranging ahead of the main body, operating as usual out of his truck and trailer rig. They rendezvoused with him in a small town of old limestone buildings and followed him down a country road for some miles. He pulled over to the side of a road just short of the goal and used his drone to reconnoiter the state park. According to online maps, several roads looped through the sparsely wooded property, connecting a series of campgrounds. In normal times they might have had some chance of claiming a site there. This year, relay refugees had clogged the place up even before hundreds of thousands of hurricane evacuees had come flooding westward along Interstate 10. It had become what in other contexts would be called a shantytown. For every official campsite shown on the map, there must have been a hundred RVs, cars, and tents. They’d spilled out far beyond the simple network of park roads and colonized green space between it and the right or south bank of the Brazos. The thin strip of public land along its north bank looked from a distance like a chalk line; it was white with pleasure craft that must have come upriver from the city. Farther north, on private farmland, more clusters of RVs and tents had found purchase.
