Anytime I long for a open face helmet...I just think of the facial reconstructive surgery. Riding a motorcycle itself is a compromise for safety, of course, but for me personally I'm not willing to compromise on the helmet. If you look at statistics on average it's over 50% of the impact to the right or left chin area.
The only time I've ridden without a jacket was for a short period at Sturgis. It was SO dang hot and traffic moved so slow.
