May not be doing too much traveling while in Austria

Why not, you may ask? Because I can't afford to buy a Eurail pass. I'm not sure how I'm going to find a pass that is affordable. I'm too old to qualify for the youth price, and I can't afford the adult price. What makes this harder is that I feel that God wants me to go on the Lourdes mission trip during 10 day. How am I supposed to do what God wants me to do if I don't have the money to do it? I need the Eurail pass to get to France, and I don't have the money to get the pass. I just wish I could find a pass that is affordable.
