To ride or not to ride?

Ok, so I've been writing about my neck injury last Sunday. I set a firm rule that if I couldn't turn my head by this Sunday I definitely couldn't do the century, because I couldn't check for traffic. My neck is much better today. It's a little achey, but I can turn my head. I was going to do a tiny ride to my LBS to get a spare tube, to see how it feels. Am I crazy to try to ride Sunday when yesterday I had to turn my whole torso to look to the left? As many of you know, being able to do this ride means a lot to me, but I don't want to be stupid about it. Could I do some serious damage? Have any of you ridden under similar circumstances? I could conceivably start with my BF and the others and drop out of I start to feel too sore...maybe even at the 15 mile turn-off...
