How do we inspire pilots to truly take up cross country soaring ?

One thing that's worked, and has been a lot of fun, is having a task set for each flying day. After the task is flown, we get together the next morning, compare the scores, watch all the flights on see you, and get some coaching from the experienced xc pilots. It's a lot of fun to "compete" against your friends. We get to fly places we might not otherwise go, and it's fun to learn from each other. At the soaring club of Houston we are fortunate that we have a cross country mentor willing to do all of the task setting, scoring, getting the projector ready etc.
