@ kurt- i really think the bias against podcasts is in the vein of a slight anti-technological bent, intentional or not. blogs aren't really that tech, they're bread and butter of mainstream media now. and that statement is not meant to detract from the high quality of this site. but i think tech solutions in the park are *part* of a solution to low budgets in some manner and i don't ever get the feeling that's accepted by the npt community.

@ lone hiker- i don't see the difference between an electronic medium losing people on a tour and a bad podcast or handheld device or whatever. there are plenty of horrible interpreters out there, i think this site may have even highlighted one of them in kansas a while back... just because a live human being in uniform leads a tour doesn't guarantee anything of quality, especially without the cash to have someone auditing a tour, let alone train them properly.
