Not quite getting it

So, The other day, I got an email from a guy who works for a company I interviewed with before I got my current job. He asked if I'd like to meet him for breakfast, only he said he'd be in DC... I know we live in a world of autocorrect, so maybe he wrote SLC on his phone, and it autocorrected to DC, so I responded back. It wouldn't be bad to meet up with this guy. It's smart to keep in touch with business contacts for networking and all that. But I'm not sure this guy caught on to his error. Here's how the conversation went:

Garrett - I'll be in DC Friday morning and wondered if you were able to join me for breakfast? I'm staying near the capitol.

Hi Steve,

Good to hear from you! I hope everything is going well for you and [Company]. I'm still in Salt Lake, so I won't be able to meet you for breakfast; on top of that, I have meetings all morning and afternoon, so if you meant SLC and not DC, I might not be able to get away until evening. If you are in DC, enjoy your stay! 

With my response, you'd think I have either helped to clear up the confusion on the location, or at least given him an opportunity to clarify what he meant. I mean, he knows I'm in Salt Lake. They flew me out to their corporate headquarters, and bought my plane ticket. That flight didn't leave from Washington National Airport (DCA), I left from Salt Lake International Airport (SLC). Also, we know each other because we were both on an emailing list of English/Technical Writing majors from Utah State University. Sure, I could have moved back east, but there were some clues.

The crazy part is, he responded  back, and I'm flabbergasted. Because, as I said, it is important to keep good networking contacts, I will probably leave it with his response, but part of me wants to respond... Here's his reply:

Another time then. I'll probably be back to DC in june

 Yeah... remember how I still live in Salt Lake? If you're in DC in June, I won't likely be able to meet you for breakfast then, either.
