I recommend everyone take the experienced rider course. There are many good reasons to do it: You must ride your own motorcycle. It's fun, laid back, and challenging. It's only one day long. It's cheap (tip: sign up months in advance, because enrollment fills up fast}. It's a great way to meet other great motorcycle riders. And it's another great reason to get on your bike.
I've been riding for 24 years, and I've enrolled in the experienced rider course 4 times so far. I can confirm that skills learned during the Experienced Rider Courses saved me from serious injuries. Specifically: Look with your eyes where you want to go, and don't look at the grill of that fast-approaching vehicle that just crossed the yellow centerline.
