Well, I've heard of fire bans before and even did camping in State Parks and such when campfires were prohibited because of fire bans. But this one is a first. We have been in a few private campgrounds that did not have a fire ring at all at the campsites. I never thought anything about it though, because the sites were so close to each other, you'd literally have to build a fire under your neighbors RV or under your own awning. There just wasn't enough room for adequate space for a campfire.
I would think any campground that does not allow campfires has made that decision for good reasons, mainly ... the safety of everyone! Sparks, ash, and foolish people in tight quarters can become a disaster real fast.
Before just banning a campground, it might do well to at least ask management why they do not permit campfires. And if you still cannot accept their logic, you are 100% correct ... choose another campground.
