Of the 6 congs I have been in throughout my life only one of the KH's didnt have Windows and this was because it was in the inner city in NYC and it was noisy and very distracting to have them.
Same here. Most halls in Toronto have windows. The exceptions are those in higher crime areas. For that matter, I can't think of any churches that are really big on having windows. I don't get what the big deal is. People don't go to church to look out of windows. And people outside who peep through windows are not usually looked upon favourably.
