I got my bahncard today in the mail, wow I looked totally hungover (the picture was taken at 9 AM the morning after an all night bender, I'll post it when the scanner gets delivered). If you're going to spend over 100 euros in the next 6 months it's worth it to pick up the card. I also just found out that it's possible to get a 28 euro "all you can travel" pass that's good for 5 people all weekend! I'm still trying to confirm this as it seems too good to be true...
