I've been to a few. My wife likes them more than I do though. Don't dress to impress.

I've only attended a few times back in my college days, no costume.

By the way, this website has a bit of a learning curve, so here's some info, in case you need it.

For members who are open to dating, certain thumbnails and profiles have a heart symbol on them with a percentage. This identifies which members are open to dating, and the percent shows approximately how compatible others are with them.

You gain website points by answering all the profile questions and writing a bio, which also earns website points, and helps other members get to know you.

Commenting on posts and writing your own posts earns more points. At level two you can private message people, and at level eight you get an agnostic T-shirt.

If you want to date, the website uses profile algorithms to find member matches, so the more details one includes, the better the match.

Many people prefer to see a written profile talking about interests, hobbies, and backgrounds that can be quickly perused to find others with similar interests..

In case you didn't know yet, to find members near you, click on the "Browse" button at the top of the page, then on "Members," and enter your preferred search parameters.
Click on the "Discuss" button, then "Nearby" to find members near you also.
Or click on the "About" button at the top left of the page to find links to FAQ or the website tutorial.

You can check for local events on the "Events" tab in the drop-down menu under the "Discuss" button, above.

Points are now being given to level 3+ members who chat. You can see chat rooms on the group main page.

Oh please don't. I remember going to one on AZ and everyone dressing in...well somewhere between Victorian and Medival European costumes and someone literally telling me to stop talking in a stupid English accent! Well I am English and this is how I talk. Very few people ever dressed like that, virtually no one ate turkey legs or had forks. It drove me absolutely sqirmingly batty!
