The Los Angeles Motordrome  aka "the pie pan" opened on April 8, 1910 near the present-day intersection of Culver and Jefferson boulevards in Playa del Rey. The world’s first elevated wooden board track built for race cars took 16 days to build and cost $12,000. A fire destroyed it in 1913. Wood, go figure? Read more here.

These canals were filled in and converted to roads in 1929 but the short line canals we rode over are visible at the left edge of the frame (just to the south of Kinney's canals)

Aldebaran Canal -> Market St.
Coral Canal -> Main St.
Venus Canal -> San Juan Ave
Lion Canal -> Windward Ave
Grand Canal -> Grand Ave

This intersection, on which two original buildings still stand, was the main entry to  Abbott Kinney's Venice of America Pier. What was different? See the redcar at the left of the frame? That's the Pacific Electric Trolley, and that's why the street is called Pacific now.

This is what used to be where the traffic circle is now.

The Race Thru the Cloud racing roller coaster was located beside Venice's inland lagoon. It was 90 feet high and had 4000 feet of track for each of its two parallel tracks. 1911

A twin-track racing coaster located next to the lagoon - 1911
