Gun Rights Policy Conference this month

Great: Support one of the most corrupt, most anti-gun cities in the nation. Money trumps everything, doesn't it?

Dan: I think you're missing the value of holding an important Second Amendment conference in Chicago (which is, as you say, an anti-gun city). I very much doubt that the decision to hold the conference in Chicago had anything to do with money. On the other hand, public perception and shoving Chicago's nose in the mud probably played a part in the decision.

Regardless of the economic impact, it means that you are in Chicago. Do you think there is a chance that CPD will be vigilantly patrolling the area around the conference, looking for conspicuous bulges? It wouldn't surprise me. I used to travel to Chicago a lot, and I always carried a gun. But I avoided going places where I was likely to get into any trouble or invite any scrutiny. There is a long list of cities where I would rather attend. That said, I hope it goes well. I've attended in the past, and found it both informative and motivating.

From SAF.org:
The conference will be held at the Hyatt Regency Chicago O’Hare Airport. The address is:

9300 Bryn Mawr Avenue
Rosemont, IL 60018.

So it is not technically in Chicago. Also, unless you are an Illinois resident with a permit or a resident of one of these states
Hawaii
New Mexico
South Carolina
Virginia
that has applied for and received a permit, you can't carry in Illinois.

About the only bright spot is that you can keep a loaded handgun accessible in your car if you have another state's permit.

IANAL. YMMV.
