I really think this is a good idea.
Witcher88 described an experience he had setting his rig up in a tent. It sounded to me like it was meant-to-be!
I remember a birthday party that I went to where they set up a tent in the yard, in case of bad weather. We had a serious thunderstorm..... and it was AWESOME; it was WAY more fun than good weather!
I also went to a wedding with a similar situation. Everybody had a great time!
Imagine how much fog you could get in a tent!
