Can we smoke cigarettes there,and is there a designated smoking area for smokers??!!

There are smoking areas throughout the grounds. Look for them on the fair map.

I don't think smoking is "allowed" anywhere with a designated area , however I've never had anyone say anything to me - just stay on the fringe and blow away - ...

I was just there for the Tiny Home Show about 3 weeks ago and noone said anything about me smoking inside, but away from any buildings. I think that changes for the Fair though.
