The wife would love to be outnumbered 19:1 or so, again. Bring singles.
Seriously, though, my place is your place for the event. As for the smoking, it will be separated and fanned. Weather permitting, it will be encouraged to smoke out doors. I will rent a tent, if need be, and have a fire pit to ward of the insect world.
If Mother Nature decides that smoking must be done indoors, I will setup the front porch as a smoke room, and there is always the covered area out back of the house.
Further, if I had to, I would, gladly, not smoke for the duration of the event if it would ensure that any and all who wish to come, do.
