County Supervisor Mark Ridley-Thomas's website has posted a multi-media feature on ten architectural sites that "define" his 2nd district. They range from historic buildings such as the Dominguez Rancho Adobe and UCLA's William Andrews Clark Library on West Adams to cultural sites such as the Dunbar Hotel on Central Avenue, the Watts Towers and Angelus Funeral Home. They also include the giant Randy's Donuts beside the 405 freeway, Pann's coffee shop and a structure I've talked about before: the Marilyn Jorgensen Reece Interchange between the 405 and the 10 freeways. An appreciation of each site is narrated by Ridley-Thomas staff deputy and developer Dan Rosenfeld.
