As VR8 was saying.....we had a good thing going with Nantahala after we sat down in person.....but ofcourse on the phone is the exact same nightmare that you're going through now. I was able to meet the new "Group" coordinator in September and he seems like he's much more organized and on top of things.... hell he even sent me a "Thank You / Come Back Again" card in the mail! Hopefully he'll respond better than the last 2 or 3 Group Coordinators did. Anyway as of right now we plan on using them again for BOTD 09.
