Graveleye, you asked in the Shoutbox about the SERA Cave Carnival.
Dates and location were announced by Maureen Handler from the stage Saturday night just before the door prizes . (I can understand how you missed it. . . I had trouble hearing much of what was said from the stage. . . not sure if it was the microphone system or the users of the system.) The event will be held June 17-20, 2010. The location is just off of I-24 at the Monteagle TN exit.
The site is the location used annually on Memorial Day weekend to host an event called "Thunder on the Rock". (Thunder on the Rock is a motorcycle campout/music festival which hosts a couple of thousand motorcycle enthusiasts every year.)
At the Cave-In there was also a notice posted at registration and I saw flyers posted in the porta-potties I visited (I assumed they were placed in all of the porta-potties but some may have been missed) and in the bathouse.
The event is being hosted by the Sewanee Mountain Grotto. The grotto had hoped to be able to announce registration info at the Cave-In but unforseen circumstances caused a cancellation of a planning meeting and registration details were not finalized in time. When the group gets it together it will be posted here with registration information. A downloadable mail-in registration form will be posted on the grotto website when the form is ready.
Sorry more details aren't available at this time but at least you can "save the dates" on your calendar. June 17-20, 2010.
