Thanks for the second comment, Cosmo. No delicate sensibilities here, but I do need to state our rules in no uncertain terms based on our experiences at the west show, when, despite our warnings, red-flag notices from the U.S. Forest Service, and the threat of jail time, we consistently find a few people building campfires (carefully blocked from view, which makes protestations of ignorance difficult to accept). I just think fire is nothing to mess with, so I don't in my replies either. We're hoping the Taylor Ranch site works out for us, them, and our attendees, and it would be sad if one selfish person wrecked it all by igniting a grass fire.
"Campfire in a Can" is a popular propane fire gizmo. It's a poor substitute for woodsmoke, but better than nothing.
The FAQ on the Overland Expo site seems clear to me:
There will be several designated fire pits run by Taylor Ranch, but otherwise no personal campfires (wood or charcoal) due to the proximity of other farms and houses and the fire danger. Propane is allowed.
So, no wood or charcoal fires. If "campfires" somehow introduced ambiguity into the statement, I'll just clarify here by stating that no wood or charcoal fires are allowed, period. Please join us at one of the fires maintained by the ranch; I think those will be great places to meet and chat.
