HALLOWEEN PARTY?!

What do you guys think??

We want to put on a big gym event along with some food and drinks and fun and games afterward that a large majority of our members would attend...

Halloween costume WOD on Nov. 1st (since that is a friday) and a gym social afterward?
Other ideas??

We want a strong community on top of a kick ass place to get a workout in so any input you guys have would be awesome!

Thanks!
