A Couple of Questions For Harrisburgers

1. When is the next "large trash" day? I looked around the exquisitely unhelpful official Harrisburg site. Unsurprisingly, I couldn't find any info.

2. When will Halloween be celebrated this year? For those who live outside the Hbg, this is not a trick question. The towns around here apparently have their "official" trick-or-treat nights on nights other than the 31st. Sometimes it's as much as a week before the actual date of Halloween, and I think the date choice has something to do with Daylight Savings Time, church, and when Penn State plays (but not necessarily in that order). Again, the Harrisburg website was unhelpful.

Any information would be much appreciated!
