I was out on a rural ride this evening and started to feel the rear rim bumping on the pavement signifying that the tire pressure was not adequately separating the two. I pulled over on a side road and broke out the spare tube and tools. While engaged in thrashing the rear wheel two different cars stopped to inquire if I needed help. The first was solo young lady and the other was a couple of young guys. I was pretty impressed especially with the young lady as she didn't know me from Adam. I thanked them both and sent them on their way as I had the situation well in hand. Still it is good to see folks who are willing to stop and offer assistance to a bicyclist broken down by the side of the road.
