this is true....
it would be a difficult event to run, but could be quite fun...
if every one met up at a set place/time, then shout go - first person to get back with the stuff wins the prize, pending print screen confirmation via a quick email or over Xfire.
could do done. or do a "hunt the dung/fruit etc" comp were you hide some dung/fruit print screen it then first person to find the dungs/fruit location and get a print screen of them selves with the dung/fruit etc and cords wins...
another comp - who can find the most in 24 hours...
theres a lot that can be done.
