Might be a little paranoid:C, but I would also not recommend that method. What if on a hot blowy day one/few rags are blown into a corner or pile up against something and start the combustion process on tinder dry grass/brush?....with you none the wiser?:shrug:
I want to know where those suckers are at at all times.:angfire:
Small door, if they blow in the only placer they can go is the floor, and when they leave, they land on the brick driveway:2tsup:. Also the rags I use don't tend to stay scrunched (Surgical sponge's, gotta love a freeby)
