DeBroglie wavelength for particle at rest

[bobaustin]

lambda = h/mv
v -> 0 means lambda is -> infinite?
So if I have an old pickup truck that moves really slow, its matter wave is huge, right?? So it's now a wave and not a particle?

I suppose if it's moving REALLY, REALLY slow it might participate in an interference experiment by passing through a double slit and interfering with itself, sure. Isn't that kind of a silly question? Quantum mechanics is for small things.
