It's the tree falling in the forest with no one around to witness it.

Hillary Clinton's "Everyday Americans" road trip through flyover country blending in with the simple folk has been so successful that no one has actually seen her.

First, how about that burrito bowl stop she made at the Chipotle's in Maumee, Ohio?

Fellow patrons paid her no more attention than a driver would get from a toll taker.

Nor did the restaurant’s staff notice Mrs. Clinton, until this reporter, tipped off that she had dined there, telephoned.

The Chipotle manager, Charles Wright, insisted at first that the tip must have been false.

So I'm asking: Was Hillary actually there?

Nor–according to this report from Gateway Pundit–did any human being apparently witness the coal-black, darkened-windowed Chevy Explorer SE van that they say carted Hillary across the Midwest:

Hillary Clinton managed to arrive in Iowa today after her 1,000 mile trip from Chappaqua, New York to Le Claire, Iowa, without anyone spotting her along the way.

Although the campaign released a couple photos of Hillary at a restaurant, no one in America spotted Hillary, or took photos of her, during her 1,000 mile road trip.

We do, however, have a certain amount of information about the van itself (aptly nicknamed "Scooby" after the animated Great Dane belonging to–get this!–an amateur detective).

The van, however, isn't an everyday minivan or even a full-sized van. It's a luxury vehicle outiftted with top amenities. 

Specifically: It's a limited edition Chevrolet Express van upfitted with a Limited SE packed by Explorer Vans company "It's very luxurious," a salesman who helped deliver this vehicle tells me on the phone. "I'd rank it up there with the best."

The model being used to chauffeur Hillary Clinton around has a gray leather interior, heated seat, a 29 inch Samsung television, and a Blu-ray DVD player. 

There is no refrigerator in the van. However, Hillary's model does feature an ice chest between the two front seats. (Which might have been used to keep her cottage cheese cold.) The middle chairs are swivel and quick release. Indirect lighting (like mood lighting) throughout the vans.

Oh, and there's a bed. The power sofa in the rear of the vehicle converts into a bed. But given the fact it's only a 6 foot wide vehicle, it might have been a little hard to get a proper night's sleep in it.

But it's not exactly great for the environment. It's a 2014 model all-wheel-drive that gets only 16-18 miles per gallon.

Indeed, because of rising regulated fuel efficiency standards, it's the last of its kind. Due to Corporate Average Fuel Economy (CAFE) regulations, they don't make them like this anymore.

But I ask again: Was Hillary actually inside this gas-guzzler?

We'll never know.

And the biggest mystery is why a presidential candidate would take a road trip supposedly designed for her to meet the people–and never meet anyone at all.
