pedeosar.......Buy one,,, dont think about it,, just get it,, it will work,,, it's not going to get red hot unless its that close to the flames, we had a simaler experience to Steve, But it was my 4 year old Grandson, i was not with them on this trip, but what happened was they were packing up ready to leave, the fire was already doused with water so all thought it was safe,,, everyone busy packing up, not realy worrying about the kids,,, when all hell broke lose,,, seems he just triped on the ring of rocks, (yes i know the ring of rocks saga) fell into the old fire, hands out to save himself, very badly burnt,, lucky the son inlaw grabed him and had him in the creek before it got any worse,,.... but still a trip to hospital, and weeks of treatment,, but like most kids, he has bounced back,,
Now, the fire gaurd,, son inlaw made one, very simaler to the one you are thinking about, his is just 4 small sheets of gal mesh,, using keyrings to join the cnrs and two snaplock things to make the final join, folded up it stores on the front of the ct,,,
I've got a pic of it somewhere, will try and find it tonight for you....
For the sake of the kids,,,, GET ONE......
