Due to Ussually Sometimes dry & windy conditions around here I Ussually choose to do My burning While Raining or snow . Best way I,ve found are using road flares , ( But I have several cases I bought at auction very reasonable ,That I keep in a safe dry storage area by thereselves ) . Takes a little longer to burn a big pile, But Much more safe this way IMO . Using paper or cardboard is not a good idea in My case anyway as the Embers get carryed away to far & to close to some of My old wooden outbuildings . Just My 2 bits .
