FWIW, the gas grills at Mountainside last winter were in bad shape. The automatic starters did not work on any of the units. It was very hard to determine if the gas was on or not. I was able to get them all to light, after finding someone with a long lighter, but only one would turn on high enough to actually cook.
I am an experienced cold weather gas griller and am aware of the dangers of gas grilling in the winter. I did not feel safe at Mountainside, but the scotch gave me confidence to make it through, luckily without accident.
Obviously the odds are that this MOC event was user error. I have used the MOC grills, and they are by far the most maintained (and probably the most used) of all MVC grills I have seen. If they took the doors off, it sounds like there was a gas build up issue. Hopefully this can be corrected.
At a minimum, I thought that it would have been nice to have a "call this number if you are having trouble with the gas grills" sticker in the grilling area at Mountainside.
