680,000-pound boulder goes on a 106-mile journey... for art.

It will ride a "294-foot-long centipede-like transporter between 10 and 11 p.m. and travel at the painstakingly slow speed of about 5 mph."

[W]ork crews from about 100 utility districts will have to take down traffic signs, overhead wires and other obstacles to let the rock pass and then reinstall them later.

A signal expert will have to move and rebuild traffic signals that would otherwise be mowed down like blades of grass by the transporter — nearly as wide as three freeway traffic lanes....

During the day, the rock... will have to park in "the middle of the road, the only place big enough"...

The total cost of the project, including the rock, the transportation and construction of the sculpture site, will be up to $10 million, which was raised from private donors....

Of course, the rock is tweeting:

I don't understand how I was NOT asked to be a part of the new season of @DancingABC. I may not move fast, but I'm graceful!

Hey, that reminds me: There's a Green Bay Packer on the new "Dancing With the Stars" — Donald Driver, along with Urkel, Gladys Knight, and Martina Navratilova.
