or what we have done in the past if nothing is really going on.......... is just tell everyone your going to a "new" spot, and drive out in the country for a couple of hours leading them back and forth. we have actually done it and it makes for a lot of entertainment, the group slowly starts to get smaller and smaller, needless to say after that we didnt have a problem for a long while after.

its better if you can get far enough out that none of the gas stations are open
