[Xastir] Shapefile Question

[Gerry Creager N5JXS]

re: Wx alert counties, what I've done on one of my web-map pages is have 
the filled county outline at a lower layer, but the county outline in 
color at a higher layer.  Works pretty well.  I'd demonstrate, but we 
don't have any severe weather in Texas right now...  :-)
