Vintage motorcycles at the LaJolla Motor Car Classic (concours de elegance)

Jeremy http://blog.1aauto.com/ has a funny caption-comment for this bike, Steam power, Check! Wooden wheels, Check! Dangerous... you don't even know!

1942 BMW r75 Wehrmachtsgespann in Afrika Korps colors and insignia

1897 Rambler Tandem

Porsches that grabbed my attention at the LaJolla concours

The 3 seater- propeller driven- 1913 Thor pacer bicycle mated to a Henderson motorcycle engine with a propeller

Strange arrangement of controls... why the rider in the back gets to adjust the speed, but can't see if the bike and riders are likely to run into anything... that doesn't seem like the best idea.

Look close at the chain, it's the only one I've seen like it. I wonder why they thought this double roller type would be better than a single link and roller

Sopwith Pup was on display at the La Jolla Motor Car Classic

If you are ever in San Diego, I recommend highly the Air and Space museum here... it has a lot of WW1 and WW2 aircraft, including the Ryan X-13 vertical take off jet

Also, stop over at the 94th Aero Squadron (restaurant) for a WW1 feel of a french restaurant with (what appear to be) WW1 airplanes (look close enough for a restaurant, but aren't authentic)
