Campgrounds - Strange Objects - What Have You seen?

[Topperace]

While we haven't been to too many RV campgrounds yet in our full-time travels (only about 40 so far), we have been to a few that have had some strange, or novel, things....

Recent stay at Helena North KOA, saw these metal Yurts they are having installed... sides have bins that they will put stones/rocks to help the anchor
to ground in high winds...will be finished for Spring next year...fairly novel idea..
supposed to be able to withstand tornado winds....

What strange or novel things have you seen?

If those were were I live you could bake bread in there!

I thought the same even here...they are supposed to finish the insides with
foam insulation on the walls/ceiling, then finish with wall board, and window and wood stove ...don't think they have intentions of putting AC in...

Looks like something you put corn in, not sleep in.

If they are a cabin, they would be hot without good insulation. Be interesting to see what they look like when done. I wonder if they will install round beds too?

I clicked on the thread thinking I would see a laundry list of "what in the national enquirer" level of stories...
Gotta start somewhere.
Just before Thanksgiving we stayed at Alabaster Caverns in NW OK and there was a decent sized sinkhole about 40' from our campsite. After going through the cave tour we found out that the main cave goes almost directly under the RV sites about 50-60'. so yeah, that was pretty interesting. The fence they had put up around the sinkhole was of the dog pen variety, but they had a special sign placed nearby that gave a history of the types of sinkholes and dangers. Just made it part of the attraction!
Also at the entrance of the cave, the rock wall had collapsed in a recent rain and blocked the whole entry. The tours were given by starting at the exit and turning back around about 3/4 of the way through.
FYI, alabaster is a pretty soft rock.

Surely I can think of some more interesting sights we've come across...
