97 Camry LE 108K miles

Yesterday I rotated the tires myself since they were starting to
feather.  Afterward I drove down the block and put air in the tires.  I
had an alignment done two months ago with the state inspection but the
tires were never moved.

This morning my wife told me there was a funny noise coming from the
car when she backed out of the driveway and hit the brakes.  I drove it
around the neighborhood but didn't notice anything unusual.  Tonight
when I went out to meet someone and go out to an adjacent town we heard
the wheel making noise as we were leaving the parking lot.  We quickly
decided to take his car instead.

On the way home it was making much noise but would quiet down when
braking.  At speeds above 30 MPH you couldn't hear much, but when going
slow it sounded like a brake lining or emergency cable rubbing inside
the brake drum.  Upon arrival home I had identified which wheel was
making noise and took off the wheel cover.  Much to my chagrin I found
all five lugnuts loose.  Apparently I had omitted tightening this wheel
when lowering the vehicle.  I took care of it and then checked the
remaining wheels also.

Total miles drived was under 10 and speeds less than 40 MPH.  I don't
suspect any damage but was wondering if anyone else had different
thoughts.  Also why would it quiet down the faster I went?  Was
centrifugal force involved?  I never felt any wobbling or other funny
sensations at all.
