We have a lot of room to operate on VHF and UHF. The most overlooked band seems to be 125cm, or 222Mc. It is a lot of fun to operate on this band, even if only in FM. It is important that we use these bands, especially 23cm, or 902Mc, where there are other secondary users that will take this band over if we don't. If "no one is on that band" in your area, but you are in a populated area, it doesn't take much to get others interested.
