I'm not sure why either, but I've noticed that too here.
The two major (community, so not things like school or the Army band here) bands in our area don't use community in their names, those being Twickenham Winds and Huntsville Concert Band. (And some in the surrounding cities. One I do remember has community band in the name, and there's a community orchestra there too.)
There's also one during the summer I play in to help conducting students, which is also really nice to play in.
(Urgh this is making me want to have a regular ensemble to play in. I haven't had one since mid July and band camp starts on the 8th at USM. The next time I'll get to play a concert here is Twick in May probably...wish it could be sooner...maybe I'll send in a suggestion or 5 and hope that we can play 1 in May.)
