Poster Duty is easy if you have a friend competing with you during it. Well.. so long as you and your friend are competitive. I got it below 30 seconds and we even kept competing after that. The trick is to turn around when it first starts out and then work yourself around to the train, because the train has 7 posters all really close to eachother (the little stand has 3 on bottom and 3 on top and then there's another 3 acrossed from it).
