I agree that neutral sites would be ideal, but it's also true that the sites don't happen by accident. As far as the West Coast is concerned, the only venues likely to draw well for the regionals are in the Northwest: Seattle, Portland, Spokane. I suppose the San Fran area might be worth a (very long) shot, but Southern Cal is absolutely hopeless in this regard. And since the NCAA can only select sites from those that apply, and those that apply presumably do so because they think they can make some dollars, it's likely that things will remain the same until WBB expands its fan base considerably. And I suspect that the relatively small size of New England/the mid-Atlantic States will always mean that UCONN fans will fill most of the seats, even if they aren't located in Bridgeport or Albany.
