READERS' POLL RUNNER-UP: AVA/Casino del Sol. Where does a band play when it's too big for Centennial Hall and the Rialto, too small for TCC? For years that question plagued Tucson--the sad reply was Phoenix--but now we now have a better answer. Set up like a smaller version of one of those "sheds" that every other city besides Tucson has, the AVA could have been a mere stopoff on the "casino circuit," with names like Wayne Newton and Robert Goulet lighting up the marquee. As it turns out, though, the AVA has hosted a little something for everyone, from tottering old folks with naturally blue hair to moshing teens who dyed it that way. A long overdue and welcome addition to our humble burg.
