Rocks?

The parks I frequent sometimes have rocks around the ring put there by campers. But, that is because the rocks were in the camping area and they picked them up so they didn't twist a ankle on one stepping on it after dark.

I sometimes put rocks under the edge of ring to hold it up for air flow. Also sometimes use rocks to hold coals in a pile, get more heat with fewer coals.
IMHO, if there is a chance a rock is hot, better to leave it in the ring, less chance of harm...

I figured it out..
Why do people put rocks in the fire ring?

Their brains are falling out. (Rocks for brains and they are falling out).

Just a serious thought.

If the rocks are big enough
Could they be laying a grill on top and cook pots on that? Kind of like a stacked down grill or my Tripod?

It's a well known way of boiling water to sterilize it in a survival situation when you only have a plastic container. Put the water in the container and heat up stones and drop them in one at a time. The water cools them so they don't melt the plastic and they transfer the heat to the water. It doesn't take many to boil the water and you're safe.

Humm,,,, I'll have to add that tip to my box of supplies and instructions I keep around for when the Zombies attack.

:B Back in the day... When I was in my early 20's. (About 35-40 years ago) We actually tried to heat some rocks and put them in the tent to keep it warmer. Didn't seem to work though. Might have had something to do with is thinking this plan up after alcohol was consumed.

I recall a scoutmaster who melted his sleeping bag doing that. He even wrapped the rock in a towel or two first and still melted his bag.

Like others said rocks are a vast improvement over garbage usually left behind.
