I've always offered help to riders I've seen stopped along the levee path, unless they're talking on their cell phones, then I figure they don't need my help. And I've had John Q Public offer me help on a MS training ride when I had mechanical trouble. The gentleman was driving a van, stopped and offered a ride to town or the next rest-stop, and I was leary about getting in the van, but one of our M/C escorts came up and said he's follow us, where-ever went, "to Kansas if necessary." So I felt better, and took up the ride to the next rest-stop where there was mechanical assistance for my troubled bike. I'm not so sure I'd get in the stranger's van, but knowing the M/C rider was back there made me feel safe. The Good Sam was being just that. There are kind strangers, just too bad the creeps have ruined our trust of most strangers.
