Note to self from last night. When finally finished with all the crap that had to get down, I through some brats on the grill for me and the boy. Stood outside talking while flipping them. Didn't think about being barefoot. Apparently all the popping you hear from the lava rock, also at times, throws little chunks out if the lid isn't closed. Stepped to flip - wow, crazy pain in left foot. Yep, one of those pieces, melted into the skin. Had to grab ahold of it and pull. Instant blister - only pea sized, but just off the ball of the foot. Hurts to stand and walk now. All Tony the Tiger like - Great! Wear shoes..
