Its all about Health and Safety nowadays, cant have a crap without some sort of risk assessment in place.
When i was a nipper we used to have a cracking bonfire in the field behind the houses in Glenburn drive, ok until they set a garage and a shed on fire by accident, so from that angle going from the fire brigades busiest night of the year its now mostly under supervision and a lot safer.
Remember the fun you could have with bangers! bangers in telephone boxes, dustbins,car exhausts, under tins to see how high they went, even being dared to hold the bloody things with yer finger tips!
Oh the danger..
