captain goodtimes, did you check all of the shows? there's a bazillion of them in chicago.
i'll take my chances with second hand pot smoke. i doubt i'll catch a buzz off the shit and if it bothers me too much, i'll just find a place where it doesn't bother me or stoop to a new low and get security involved.
as for cigarette smoke, it's everywhere i go now, so that doesn't bug me at all. this is not to say that i still smoke, because i don't. i quit 9 days after i found out i was knocked up and haven't touched one since.
