Not sure if anyone from on here goes to this. They have it every August and March at the Crowne Plaze Hotel in Cherry Hill. I've been going for a few years now, it's pretty rad. I keep trying to get a hotel room but they sell out pretty damn quick. I've had some pretty epic experiences there. My favorite is when Malcolm McDowell held an elevator for me and smoking a cig with Dario Argento. They have a REALLY great dealers room and sell all kinds of horror stuff and other things that would peak the interest of a horror hound. Every convention has a different reunion of different horror movies(Well mostly, the one in August had a Boondock Saints reunion, so much fun!). They have Q&A's, all that good stuff.

Here's the site. I'll try and post some pics in the next couple of days.
