Well, when the young 'uns moved in next door... they learned early that if they went NEAR those barrels, they were never gonna be allowed to visit Miss Cheryl ever again...
(but those barrels all had the metal clamp retaining rings with PADLOCKS!!)
Even when their little cousins visited with them (and me), the Neighbor kiddos gave their cousins 'the lecture'... (huge extended family!)
They are now 11 and 14, and still give them a Wide Berth!

It is a privilege for the entire 'crew' to be able to come inside and 'play' with some Cast Iron Toys!
They are fascinated by those real toys and the toy stoves!
(they also are fascinated by the 50" Flat Screen in the garage where my Electro's are... (which are always turned off when they enter)....)
And for good measure the back yard is Fenced in, and had gates padlocked if too many munchkins were running around and I was outnumbered!

PS... Yellow Cap Easy off I presume...?
