Lobster Boy
Jen and Tom found a cute "Lobster" Halloween costume for Tristan. The bad news is that he is already too big for the outfit, so it had to go back to Baby's 'R Us. The good news is that we got some pictures first...

Hacked!
Arghhh... We got haCkED! Here is a snapshot of what this site looked like last night. Hopefully all is well now. Sorry if anyone was offended.
Spending the night fixing it....

Engineering fun
Only Tom's engineer friends will appretiate this story:
RAILROADS
Does the statement, "We've always done it like that" ring any bells? Read this email to the end; this is a new one for me
The US standard railroad gauge (distance between the rails) is 4 feet, 8.5 inches. That's an exceedingly odd number. Why was that gauge used? Because that's the way they built them in England, and English expatriates built the US Railroads.
Why did the English build them like that?
Because the first rail lines were built by the same people who built the pre-railroad tramways, and that's the gauge they used.
Why did "they" use that gauge then?
Because the people who built the tramways used the same jigs and tools that they used for building wagons, which used that wheel spacing.
Okay! Why did the wagons have that particular odd wheel spacing?
Well, if they tried to use any other spacing, the wagon wheels would break on some of the old, long distance roads in England, because that's the spacing of the wheel ruts.
So who built those old rutted roads?
Imperial Rome built the first long distance roads in Europe (and England) for their legions. The roads have been used ever since.
And the ruts in the roads?
Roman war chariots formed the initial ruts, which everyone else had to match for fear of destroying their wagon wheels. Since the chariots were made for Imperial Rome, they were all alike in the matter of wheel spacing.
The United States standard railroad gauge of 4 feet, 8.5 inches is therefore derived from the original specifications for an Imperial Roman war chariot. And bureaucracies live forever.
So the next time you are handed a specification and wonder what horse's ass came up with it, you may be exactly right, because the Imperial Roman army chariots were made just wide enough to accommodate the back ends of two war horses!
Now, the twist to the story
When you see a Space Shuttle sitting on its launch pad, there are two big booster rockets attached to the sides of the main fuel tank. These are solid rocket boosters, or SRBs.
The SRBs are made by Thiokol at their factory at Utah. The engineers who designed the SRBs would have preferred to make them a bit fatter, but the SRBs had to be shipped by train from the factory to the launch site.
The railroad line from the factory happens to run through a tunnel in the mountains.
The SRBs had to fit through that tunnel.
The tunnel is slightly wider than the railroad track, and the railroad track, as you now know, is about as wide as two horses' behinds.
So, a major Space Shuttle design feature of what is arguably the world's most advanced transportation system was determined over two thousand years ago by the width of a horse's ass.
