Wow. I'd very much like to experience 34 North 118 West [via freegorifero]. From the description:

"Imagine walking through the city and triggering moments in time. Imagine wandering through a space inhabited with the sonic ghosts of another era. Like ether, the air around you pulses with spirits, voices, and sounds. Streets, buildings, and hidden fragments tell a story. The setting is the Freight Depot in downtown Los Angeles. At the turn of the century Railroads were synonymous with power, speed and modernization. Railroads were our first cross-country infrastructure, preceding the telegraph and the Internet. From the history and myth of the Railroad to the present day, sounds and voices drift in and out as you walk.
