Intervention is an annual event celebrating Science Fiction, Fantasy, Pop Culture, and the Art that surrounds them. Come meet the creators, actors, developers, and producers of your favorite works – and also learn about the process of how it’s all made. It’s a 3 day fandom party for nerds and geeks of all types.

Programming Spotlight: Con Runners’ Track

This year, Intervention is introducing a new set of workshops and panels specifically for people who want to run conventions of their own! Join our panelists for six panels covering everything you want to know about kicking off your own conventions, from business to common pitfalls:

So You Want to Run a Convention? will guide you through everything from concept to post-con, helping you avoid some of the more common beginner mistakes many encounter.

Attendee Policies will help you learn how to keep your con safe and organized without being overly strict, from security to crowd-herding to medical help.

Leadership Strategy in Volunteers will teach you how to recruit and manage volunteer staff for your events, how to keep them motivated, and how to handle difficult volunteers.

Marketing and PR will teach you what to do on the other 362 days of the year: how to get the word out and bring people to your event.

The Horror Stories panel will be a time to share the worst of the worst when it comes to your previous experiences — and learn how to avoid these issues, or what to do once they’ve begun.

And From Bad to Worse: Tales from Running Conventions and Conferences will explore real-world examples of issues that could stop a con in its tracks, and how our con runners recovered from them.

Check out our programming descriptions for more information on these and more!

Children’s Programming for Intervention 6

Overall Theme for this year: Spy Camp

Friday Night:

Welcome to Spy Camp!
Calling all secret agent wannabes. There will be a secret meeting held this evening for you spy enthusiasts.

Friday evening will be the kick off to our spy filled weekend. Children will receive their special spy packet, name, and learn our sacred oath.

10:00 a.m.-1:00 p.m.- Mastering the Art of Disguise.

We will be experimenting with our looks and trying out new disguises to learn the way of the spy. We will try our hand at paper mache masks, felt mustaches, maybe even some face painting. Anything that can boost our spy persona.

1:00-2:00 – Out for Lunch
Becoming a spy sure works up an appetite.

2:00-5:00 p.m.- Spy Training

Now it is time to get down to the nitty-gritty. This what being a spy is all about!

During this time we will learn how to decode secret messages with our decoders, practice the art of interrogation, learn how to read fingerprints, and try some spy experiments.

5:00-6:00p.m.- Field Training

Now that we put our brains to work it is time to workout our muscles and nimbleness.

This event we will have a “lazer” maze challenge, “bomb” defusing session, and a little bit of target practice.

9-12 (possibly longer)

Big Caper Day

Today we put all of our training to a test as something has gone awry and they need our expertise in solving the crime.

This will be a scavenger hunt that will spread out through the convention. It will use some of the skills the children learned from Friday and Saturday so we encourage you to participate as much as possible! Feel free to have the kids dress all in black this day too so that they can get into their spy role.

In addition we will have a special Doctor Who themed mystery challenge as well.
