We had about 150 or so, but I give out probably 7 to 8 pieces at a time. We buy the big bags at Sam's (Hershey's, Reese's, Kit-Kat, Twix, M&Ms, and Almond Joy, I think that was the assortment this year). I guess we spent roughly $80 on candy.
But, in my neighborhood, it's mainly kids 10 and under. They are all very polite, dressed up in little costumes, and their parents are either at the curb or three feet behind them. We even had a parade that morning with ATV's pulling trailers. My wife and I dress up (I'm usually a penguin, this year I was Julius Caesar), I've got a football game in the background, and I'm enjoying a nice adult beverage as well.
Halloween is a fun time for us. Probably because we don't worry about vandalism, 15 year old's without costumes, or anything like that.
