tomato woes

I am so envious of people that can grow tomatoes.  Our yard gets lots of morning shade and direct afternoon sun from the south, the kind that roasts the plants!  It also gets poor air circulation.  Success only comes with grape and cherry tomatoes in containers on the deck which is a story above the back yard.  Every once in a while I can get Romas to grow and produce, but not this year.  Here are how my tomatoes look - pretty from a distance, but close up you see the rot.
