Hi all - I like to consider myself a mildly seasoned traveler (salt and pepper, a little hint of cayenne), but I have yet to travel to or via Chicago O'Hare! I'm heading through that way tomorrow and need help.

I need to go from Terminal 1, Concourse C to Terminal 2, Concourse F. Every map and website that I've come across doesn't explain at all how I'd get there. Do I have to end up going back through security and will 90 minutes suffice?

I love to travel, but I hate having to go through airports that I'm not familiar with. Any help would be great!
