Agree that wins a prize for "ugly". You may have something more serious than just early blight going on there. I can't be sure but much of that looks like fusarium wilt to me - it is in your soil. Check out the link below for more pics and control recommendations. Good luck.

digdirt, you're probably right. Verticillium wilt is probably the culprit. You should see my garden now. Almost all the foliage on my tomatoes is dead. It's disgusting.

Short of fumigation (which seems way too expensive for a small garden), what other options do I have? I'd hate to think I can't grow tomatoes anymore, but that may be the reality I'm looking at after three years of this.
