In years past, we’ve toured a several distilleries and sampled fine whiskey, visited the Devon’s Desi corridor and the Northeastern Illinois Regional Crime Laboratory, toured the Nielsen-Massey Vanilla Plant and the Sketchbook Brewery Company, enjoyed a wine and olive oil tasting, taken a walking history tour of the 1800s town of Long Grove, created stained glass works-of-art, shot guns, enjoyed ethnic cooking classes, and visited architectural gems. Our coördinator can also provide you with information for a self-guided walking tour if you wish to venture into the city. Sign up soon or there may not be any spots left. The deadline is October 19th, but may close earlier depending upon demand.

Book A Room Now.

We continue to be excited about the venue. The Westin Chicago North Shore Hotel in Wheeling has a lot to offer. It hosts other events we know of with comparable size and similar people, and we have worked with some of their senior staff as well as the people behind the scenes who do an amazing job helping us volunteers to keep things running smoothly. The hotel room block is set up and ready for your reservations. Problems with reservations may be forwarded to The Hotel Liaison../images/email-regular.s.gif for timely resolution.


Do you have a special area of expertise or something you’re passionate about that you wish to share with your fellow Mensans? WeeM is the perfect opportunity to do so. Simply fill out the Speaker Form and our Program Chair will get back to you. If you have any questions about being a presenter, just e‑mail our Chair../images/email-regular.s.gif.

Too Much TV is Bad for the Children So …

Bring the kids! Chicago has been working with several dedicated volunteers to create a kids' track at our functions. We've ironed out the details during our Monthly Business Meetings during the year and are pleased to offer you and your kids a wide variety of activities throughout the WeeM weekend. Babysitting will be offered during certain events, and WeeM speakers will deliver programs tailored for the kids.

The Best People are Our Volunteers … How About You?

You may not see them, but you see what they do. Volunteers are the caretakers of our amazing, four-day event! They earn collectible WeeM pins and entries into the Volunteers' Raffle — double entries for wee hours. They are adored by WeeM ghosts and goblins, and are protected from evil spells, light sabers, Vogons, etc. So why not plan to volunteer for a few hours and then contact us this fall! Peruse the PAAG to figure out which programs you’d want to attend when figuring out your volunteer schedule.

Attention Vendors!
Our Vendor Coördinator is accepting applications for space at WeeM. Refer to our Vendor Flyer for all the details. PayPal is required to submit your payment. The deadline is October 12th.

Help The Economy!
