Have you guys seen the PBF podcasts? They're ~1hr long interviews from lots of folks in the backpacking community. I haven't listened to all of them, but there's lots of good info in there. But the real reason for the post is do direct folks to the JRB interview...
For those of you not familiar with podcasts, they're audio files that you download onto your computer or mp3 player. Just click it open and listen to it. I open it on my laptop to play in the background while I'm posting to the forums, making gear, etc.
The PBF forums are pretty good, too. Very strictly on topic and some pretty strict rules if you're into that (and y'all thought I was a topic-nazi), but the info is good.
