Yep Mastertangler, I can see how sandals could be a problem, for me I've always thought of a boot full of hot soup and trying to get the laces undone.
So far this summer I haven't been able to take it camping but that Littlbug sure impresses me playing with it on the lawn. My main goal with it is to have a way to have a small fire under my tarp on rainy days. Of course if my old kerosene roarer stove craps out I'll sure use the Littlbug for cooking too. In all my fiddling I've had a large pot of water on top, any number of uses for hot water and the pot acts as a flame deflector. Wouldn't want a straight shot up to my beloved synthetic tarp. Holding my hand above it, all around, I can't feel anything more than warm. We'll see, wouldn't be the first time one of my ideas didn't work out.
Best Wishes, Rob
