It's free, it's fun, it's rewarding, it's family time, it's sort of small club of people, it's peaceful, it's challenging, it's teamwork....oh yeah - and it's free and fun!
---it's nice to see that other people care more about the environment, spending time with their families, hiking around, etc...than hanging out at the mall wasting money and energy on useless disposable items. I think it's really rewarding to know there are others out there like us...
