I called the Pasco County Sheriff's Office today to find out what the hours are for trick-or-treating this year. After getting laughed at by the operator, I talked to someone else that informed me there are no set hours for trick-or-treating here in Pasco County, Florida.
I'm just writing this post to help anyone else out that may be looking for the same information, as it's not really readily available anywhere else. So if you're waiting for a certain time to take your kids out...just go! :)
