I've always had a few of those what if thoughts out on long rides, this usually happens just after I've been buzzed by a car. My normal supplies for a ride are 2-3 bottles, $20, iPhone, and a repair kit. Time to add this to the list. With the amount of time I spend training alone why didn't I have one of these sooner. Thanks Jenn.
