Hosts Mike Graupmann and Ralph Hardesty present another info-packed slate of heady entertainment, this month investigating the iron horse and the changes it brought to a burgeoning nation. Joining the regular gang of wit and wisdom this evening are guests Spike Gillespie, Anis Mojgani, Nina McConigley, and the Alamo's Lars Nilsen(!) More fun, we reckon, than Casey Jones with a steam-powered catheter. Thu., Nov. 8, (8:00) (2012). $6.
