There is a book called EZ 66 Route 66 Guide for Travelers and I am in a Meet Up group for Route 66.
Located just east of the Rialto City limits are the concrete Tee Pees of the classic Wig Wam Motel. This icon has come under the care of a couple who are dedicated to preservation. The couple has renovated the Wigwams and there are two motels on Route 66, similar to this one and the motel is the last of the chain built and are a testament to the re-emergence of Route 66.
After you leave the Wig Wam Motel and head west, there is a mixture of shopping centers and older buildings that once were garages, gas stations. There are still old motels with quaint names and examples of bungalow courts. Along Foothill Blvd., there are many instances of the Route 66 sign and also wall art of past days.
The Sycamore Inn dates back to 1848 and was originally a stagecoach stop.
