A canyon in Los Angeles County, California, south of the city of Chatsworth. California Route 27 (also known as Topanga Canyon Boulevard) runs south from Chatsworth to the Pacific Ocean. Probably the inspiration for the Reebok Topanga hiking boot. Ironically, given that the name is an inspiration for a Reebok style, there is a VANS Factory Store on Topanga Canyon Boulevard. I ( Charlie) have been by (while on a business trip) but it wasn't open at the time.
