Know your equipment! The little red flashing taillight that keeps 18 wheelers from running over me stopped working so I stopped at Kroger to buy some batteries. Well it doesn't take batteries! It recharges via usb. So I'm sitting in the shade at Kroger recharging when I could have done that last night. This is probably the nicest Kroger that I've ever seen - even nicer than Rome, Dene.
