Hmm, maybe we need to use a new character for ranges.

>>> In Hawaii, addresses outside of the city of Honolulu use a two-digit prefix in addresses to determine which sector of the island an address is located.  So an address might be something like "99-123 Kamehameha Highway".  Would this scheme work for an apartment complex that's addressed something like 99-100 through 99-200 <Street Name>?
