After taking a hard look at the schedule of events, I think I'm going to hold off on the bahncard for the time being because my sister turned me onto the bus and also told me that I'd have to buy her train tickets.

On a train related note, I want to try and get down to CGN to check out the 31. Internationale Ausstellung für Modellbahn und -zubehör.

Thanks again for all the input.
