While not technically legal, you could use them on one of the FRS frequencies.. I say not technically legal because the baofengs are not certified for use on FRS/GMRS frequencies.

The FRS freqs are unlicensed and used mostly for playing around, so I doubt anyone would notice. Even then, I wouldn't use it for commercial purposes, as I've seen descriptions of FCC tracking down and taking legal action against businesses using unlicensed frequencies.
