Now you may be onto something with the mat (in Alaska people put a log or other object they can drive nails into in front of the doors of cabins when they are vacant for a time). Something similar might work around a smoker, that one could fairly easily remove for their convenience.
i saw that, theey had a DIY where nails and 2x4's were being used.. i can see if the smoker was placed on a cement slab, the "spike strip" so to speak could be bolted down onto the cement for an over night smoke and then easily unbolted in the a.m. just remember that you have them down when attempting to add wood or wear puncture resistant boots just in case..some of them sleepy exhausting night smokes you stagger out and arent fully awake yet to add wood and YIKES!! instant awakening! lol.
