It's cool that YC has produced enough services to allow you to do this sort of thing.

One thing that I found interesting were the gaps in the trip. The most economically "important" pieces were skipped over. Things like the airline service, fuel consumption, and potentially more innovative ground transportation. The companies that made products and services that "actually" got you to Mountain View and back.

It will be interesting to see if YC can produce companies that start to close these gaps.
