Does anyone know if the Astros will continue to have throwback uniform Fridays? I really like to see the Astros in the retro Colt .45s and rainbow uniforms as well as the blue and gold of the Bagwell/Biggio era. I think Throwback Fridays is a great promotion and it goes a ways in showing off the heritage of the Houston Astros. Jim Crane would be wise to continue with Throwback Fridays.
