Posters can be printed in low volume very cheaply on a large PC printer. I've used my Epson to print long banners so posters shouldn't be a problem. I hope that the recent cuts don't go as far as keeping the poster frames empty. Here's an idea. How about Amtrak soliciting the cities that they service that are looking to build up tourism? Give them the poster space at a low cost and maybe they will bite. If you look online you will find travel/vacation posters for Chicago "The Vacation City" , MIAMI, Denver, New Orleans and many other destinations. This idea for trains may be a throwback to an earlier time but the airlines still seem to do it.
