began with a day in Golden Gate Park, including a visit to the California Academy of Sciences
and wildflowers on the roof and a view across the park with part of the
solar cell array that provides some of the power for the museum.
Just one of many exhibits.
The thousands of ladybugs displayed to show the different pattern of
spots that you may find.
We didn't check all of them but we didn't find any two that matched.
A mud skipper, only a couple of inches long.
The large tanks had a wide variety of sea life.
An albino alligator
had lots of hands on science displays.

The Babbage Engine.
Designed by Charles Babbage but not completed until 2002, 153
years after he drew up the plans.
The array of gears, levers, rods, and pins can be set to calculate
using the method of successive differences.
It permits calculation of complicated functions without using
multiplication or division.
It was intended to solve equations like these to produce tables that
were widely used prior to the development of computers.
They are still used inside the computer but you just don't see them.
The computer is powered by this crank (the mechanical device not the
guy, he was friendly and informative).
The program is controlled by the set of cams on the right.
Slide rules, hand held analog computers.
A replica of the first transistor
Early personal computers and some of their spawn.
This one is by Ohio Scientific and looks like the prototype of the
first PC we owned.
PDP 11 a workhorse at Brookhaven for many years.
Inside a Cray-1 computer.
The length of each of the blue web of wires were selected to ensure the
timing of signals was correct.
A fog bank covered the bay when we arrived.
As we set out we noticed the surfers below.
About here some people started to comment on their acrophobia.
If you hang way over the side you can get this view.
But this platform is safer.
The cables that suspend the roadway from the main support cables.
More than 1/2 way across.
A group of kayakers going out for a day on the bay.
We took a day trip to Sonoma
A museum in a park there had this replica of an old time classroom.
The Sonoma area had a couple of other stops that you can see on

Because of all the changes only 160 rooms remain of the 400 to 500 that
This view from a upstairs window may give you an idea of some of the
Stained glass windows and doors were everywhere.

Few of the original furnishings remain.
Because of her eccentricities and the continual changes there are some
inexplicable architectural features.
a stairway that goes up to the ceiling, separate doors for
people of various sizes, others that open to reveal blank walls,
and this switchback stairway that has 42 steps each 2 inches high.
Some of the glass decorations in the gift shop.
We were treated to a barbecue lunch and then took a walk along this
path through the redwoods
Followed by an old time train ride
through the forest.
Some folks spent part of the trip practicing string figures that I had
learned during our visit to the South Pacific.
Along the way we came on these desperadoes stealing lunch and gold.
But granny grabbed a shotgun and took them down.
A tunnel near the end of the line.
The ride ended at the Santa
Cruz Beach Boardwalk
and amusement park on the ocean.
