their way back to their original home. I don't know if I believe that
but would like to know if there is a satisfactory distance to go out

Experiment.

Spray paint your next batch of 3-mile chipmunks green.

If, thereafter, you see a green chipmunk (and haven't been drinking), go for
red and four miles.

Me, I'd dangle 'em from Helium-filled balloons and let the next state worry
about it. To avoid animal cruelty concerns, fit each 'munk with a teeny
helmet.

You can also think "Cat."
