My First Tomato

What is that? That is my first tomato of the year with a big bad spot on the side of it. This tomato is about the size of a golf ball. The larger it grows, the larger the bad place gets. I'm tempted to pick it now and toss it out. Maybe, a new tomato will grow in its place. My first tomato of the season and it's already rotten before it reaches puberty. It figures!
