BAD Places for First Dates

I haven't been on a lot of first dates, but I remember one that made me realize this isn't a good place for a first date. I had my eye on this girl for a while and asked her if she would like to hook up some time. Well, that weekend my family was having a  family BBQ. I'm talking about the kind of family BBq''s where every cousin you ever knew was gonna be there.  So, I picked her up for our first date and took her to the BBQ. Bad mistake. First of all, everyone at the BBQ thought that we had been dating for months and asking all these questions; this poor girl barely knew me. But, I put her in this position. NOT a good place for a first date. What are other BAD PLACES for first dates?
