A San Diego MTS / Metropolitan Transit System city bus near the Interstate # 5 / Pacific Highway. San Diego Californa. June 2013., a photo by Eddie from Chicago on Flickr.
I took this photograph during my recent vacation to San Diego California back in June of this year.
The San Diego MTS / Metropolitan Transit System operates these modern and very colorful city transit buses, that are fueled with environmentally friendly compressed natural gas. (CNG)
