100% grass fed beef. Icky! Am I crazy?

I went to the greenmarket in Union Sq today and picked up a bunch of stuff. I was about to hop on the subway when I decided to text my SO. As I stood there, the seller nearest me, offered his "shade from the sun" while I texted. Then I got lured into buying his beef. I must admit that I had heard the grass fed beef might taste odd to most of us not used to it. I decided to buy the beef patties, because I did not want to spend more money if the meat wasn't to our liking. So, here I made a delicious cucumber salad, a potato salad, and jalapeno butter grilled corn. I sliced the sweet onions an heirloom tomato to put on top of our grilled burgers. We sat down and took one bite each and looked at each other with faces of disgust. We hated the taste of the meat. I seriously put my burger down and said "Let's order pizza". I figured the salads and produce would hang well until tomorrow when we can make burgers with meat from our butcher. But, am I crazy? Am I missing something? We do try to eat organically and we do love adventurous food. But we just did not like the beef. I almost feel wrong for not liking it. Thoughts?
