Has anybody else noticed a substantial increase in milage when following a semi truck?

I have a 2007 Explorer and it has the instant MPG readout. When I follow a semi on Interstate I immediately notice a 2-3 MPG increase if I pull in behind an 18 wheeler. Here in Ohio they are are supposed to go 55 and usually go about 62.

This is with out the TM behind me, but even with the TM I see 1-2 MPG increase when I follow a semi.

I know it is the draft, like you hear them talk about at every race but it still amazes me and even though I don't like following something I will on occasion.

The other thing I notice is that I get a 2-3 MPG change depending on if there is a wind behind me or I am going into the wind. The Explorer is kind of like a box on wheels and the wind makes a big difference.
