UPDATE: it's not a Scavenger Hunt but a Photo-Challenge! click HERE to read update :)
and so on the stroke of Halloween-midnight (12noon-ish Singapore time), the Pumpkin has disappeared and has been replaced by a "cross country" Scavenger Hunt! this is what is shown now on the Dark Knight-viral website: WhySoSerious.com:
while you may not necessarily have to transverse across 21 States in the US (that would be uber-fun tho, IMHO - and utterly insane as well :p) participants are to submit photographs of the locales/objects from the given clues - which can be found/deciphered by clicking on each individual cut-outs peppered on the page (which reminds me of a scene in Tim Burton's BATMAN with Jack Nicholson's Joker shredding away in his lair LOL) - for which i have saved as individual images which you can use HERE / or my FACEBOOK Album (just send me pics when you're done, please LOL) ... and remember, you can't start before daylight (as the note mentions) becoz im sure the camera-flash's gonna giveya away LOL ... no email-address were to be found on whysoserious tho ... or would it be firstname.lastname@example.org? (from the ibelieveinharveydent-era?) ... *hhhmmmm* = *good luck, clowns!*
