LOL, Shane –
Here ya go, Shane: Zombie Strippers
I organize ZombieWalk Columbus. It's an annual thing and I have always planned it in the spring because awesome weather makes it easier to get people outside. Participants as well as innocent bystanders. Plus, it's a great half-way to Halloween horror fix for a lot of people.
While I don't have any kind of haunt affiliation, there is one that I try to plug regularly during the Halloween season. I totally agree that it would be a great idea for a haunt to try to organize something like this. ANYTHING you can do in the off season to remind people that you're still around is a good idea. Haunting and zombie walks go together like porn and Jergens (hahaha, shane). A zombie walk, or even a non-descriminatory all-hands-on-deck 'monster walk' would be a decent way to estimate public interest, hand out literature directing people to your site, and/or find new actors (and find them EARLY). I think the only obstacle a haunt would have to overcome would be the approach. Haunt advertising tends to focus on the scary, and it should. However, for an event like this, at least if it's done in the off-season, I think comedic, ironic, fun, and even family friendly is the way to go. People aren't thinking about fear for fun yet. They're thinking cookouts on the patio, family functions, and being social. If you can develop an approach that works for you, I think it would work out great.
GAH! I could write PAGES on the questions you have, but I've got some stuff to do this morning. If ya wanna shoot me an e-mail sometime I'd be obliged to have my brain picked (brain pickin' is what zombies do best).
To look meant danger, to smile meant death!
