What you can get at the visitor services desk
The most useful resources for first-time Route 66 travelers are the free driving guides specifically covering the Texas Panhandle stretch. These guides are typically printed locally and updated periodically by the Barbed Wire Association volunteers; they include the historic Route 66 alignment routing through McLean and the surrounding towns, GPS coordinates or detailed directions to the major landmarks (Devil's Rope Museum, restored Phillips 66 station, Cactus Inn Motel, Red River Steakhouse), and notes on which sections of the original alignment are still drivable versus which have been replaced or removed.
Free maps cover both McLean specifically (a small fold-out showing the historic Route 66 alignment through town, the major landmarks, and walking-distance relationships between them) and the broader Texas Panhandle stretch from the Oklahoma border at Texola through Amarillo and on to the New Mexico line. The Panhandle map is particularly useful for travelers planning multi-day Route 66 itineraries, as it shows which towns are worth dedicated stops and which can be passed through more quickly.
Beyond printed materials, the volunteer staff provide verbal recommendations based on traveler interests and trip context. A Route 66 traveler heading west toward Amarillo will get different recommendations than one heading east toward Oklahoma; families with children will get different suggestions than serious photographers or architecture enthusiasts. The personalized recommendation service is one of the genuinely valuable features of the McLean visitor information setup.
