Enabling rtree should be no different from disabling it where weather 
alerts are concerned.  When draw_shapefile_map is called to display an alert 
county, all rtree indexing is skipped --- we already know which shape to 
display, so there's no point looking it up in the spatial index.

If there's a noticable difference in this behavior with and without 
rtree, then there's a mistake in how that skipping is done.  Please let me 
know if that's the case.
