I like old trucks, so I went across the road to take this picture.

I was on the dirt shoulder of the road.

When I got back on the road, I started hearing a "thumping" sound on the left tire.

I thought it was just a piece of gravel stuck in the tread.

It turned out to be about a dozen thorns imbedded in the tire.

Each thorn was about 1/4 inch long.

I pulled each one out and had no punctures to the inner tube!

They say the Schwalbe Marathon Plus tires with thorn-resistant tubes are pretty good.

I think I just proved it!
