Good looking solution! I have tried similar, but most of the time I'm also dealing with 25 mph winds with the rain, so no go with umbrellas. If I must smoke, I use a small popup tent anchored with heavy weights and extending partially under my garage overhang. So far, so good, but I've been a bit nervous when the wind hits hard. Only have had to do it a few times in the past few years though. I try to time the weather.
