Think of products that used to be popular, but you don't see much anymore. Um, like, yeah, well...8 tracks! Safety pins always seemed to find their way onto scavenger hunt lists that I was a participant in, but they were just with kids running around bothering strangers.
Guess Rendition Verite 1000s and Voodoo II's wouldn't be a hit with the American Legion crowd, eh?
Is this a 'run door to door' hunt or a 'you have a week to find' type? I've seen both employed, the former was kinda fun, the latter turned into an episode of Oprah with everyone wanting to tell their story about how they came to dig through boxes to find each item. Bah to that.
