- Seattle, Washington
- New Orleans, Louisiana (I drove by once.)
- Minneapolis, Minnesota (I may have been there actually, but not in my adult memory.)
- Los Angeles, California (Yes, I've lived in California for five years and never been to L.A. Most people in SF tell me I'm not missing much, so there's not a lot of incentive. Still, it comes up in conversation so often, it seems necessary.)
I may have to go on a U.S. tour. Although, I'd prefer one at a time. Toledo, Ohio would be another natural for the list, of course, but I'm going there in June, so I practically have it covered.
