LONGHORN SLAP SHOT VERITE: My brother, cited in this space yesterday for having spotted an Elvis impersonator at an Arkansas hockey game, today sends me this suggestion for filmmakers: "There is a possibility for a great documentary about hockey in Texas....Nobody in Texas knows the rules to hockey, but there are more professional hockey teams in the state than any other. Make a documentary following these bush league Canadians, Russians, and Yankees through long road trips from El Paso to Austin to Corpus Christi to Waco to Laredo to Fort Worth to Shreveport to Albuquerque. Meet the 'hockey chick' groupies. Watch the beer flow in small arenas. Meet the rednecks who come to see the fights. Interview the church groups and the Cub Scout packs. Cover the hundreds of loyal Laredo Bucks fans who cross over from Mexico for the games. (They even have a Spanish edition of their webpage. Do a keyword search on 'Hockey esta Noche'!) Show promotions far better than any minor league baseball team or stock car race has ever known, Elvis impersonators included. Make it surreal. Create the Texan response to Bull Durham."
