one time my friends and i ran out of things too do....we ended up playing mousetrap (yes the board game) in an alley beside the movie theatre and then a gang of guys that had obviously been smoking walked over and started placing bets on us...then we gave up cuz we had to go home and they started arguing over who they bet on and we left
Friends a while back(years) made a cardboard cut out of a little boy that we took pictures with polaroid camera'*. the idea was to take a bunch of pics with you and him
with something in the background that reprisented your city/town.
then mail him with photos to someone out of town. and so on and so on.
it would work so much better now with digital cameras
