Dan,
Great idea, I don't care how much they cost, but I was thinking of leaf debris etc. building up inside the side sill area. I wonder if it would build up enough to ignite? Price is great, I know how much it takes first hand to get a product to market. Unless you can sell 1,000+ units, the cost always seems more than something you could pick up at OSH that costs a couple of bucks made overseas. So would you be able to blow out debris from time to time with an air hose?
