I have looked in several stores for a grill mat to place my smoker on but I have not been able to find one, probably not the best time of year to try to buy one. I can order one online, but I am planning on my first smoke this weekend (tomorrow actually) and it won't be here in time. I have a large front porch where I plan on putting the smoker. It is cement and brick so fire won't be a problem. My concern is what will drip onto the cement. Is there anything I can use until I can get an appropriate grill mat?
