h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

This rock looks heavy. You would have thought they might have found something a bit lighter, to cart from place to place to mark the fair.

These days, of course, when you want to tell people where the next market or fair is going to be, you just put a notice on social media.

This picture rocks!

I have a menu board that I put notices on sometimes. It's in the shape of an A-frame, so it will stand up on its own.

This particular rock deserves to be celebrated because most rocks stay wherever the glacier left them, or wherever the old farmers put them when they built stone walls. Imagine how many strong guys must have been needed to lift the rock onto whatever cart was going to be used for hauling it to its net destination.

They could have drilled a hole through it to put an axle through and have it on wheels permanently.

Did you know that in Cornwall, a county in England, there is an ancient stone circle made up entirely of milky quartz blocks like this?

I did not know that. I'm still trying to cope with the idea that the stones at Stonehenge were moved to their present location. Or that the pyramids were built before the days of modern technology.

And yet, it doesn't seem as if rocks move around as much as they did way back when.

Small rocks are very mobile even now.
Every time I hold a pair of trousers or jacket from my youngest son upside down, rocks and pebbles rain from every single pocket.

He intends to build a house for the mice and is collecting building materials.

I would never dispute the mobility of small rocks. neither, if he were still alive, would the young David of Biblical fame.
