Sorry to hear about the crash. But don't feel too bad. It's happened to a lot of us. Fr'instance, about a month ago, I came to an intersection, thought I could slow down and balance until the car passed, and well, I didn't. I fell over, right at the intersection. Similarly, the people in the car stopped, asked if I was okay ("I'm good, but my ego is a little bruised"). Luckily DH was far enough ahead of me that he didn't actually see it, and so he couldn't harass me about it. The big lesson I've learned? Don't panic. You've always got more time than you think, and as soon as you panic bad things happen. Of course, I learned this lesson the hard way (well, okay, it took me a few times, as I'm a bit of a slow study.... ).

Don't worry about it. You'll get it. (If you're feeling nervous, practice a little in an empty parking lot before you go out on your ride.) And good for you for finishing the ride, and even better for wanting to get back out there!!
