So my daughter and I went for a ride to get some breakfast. Instead of sticking to the streets I decided to take a "short cut" down an unpaved trail that runs along the wash. I saw those low-lying plants and said to myself "Hmm... those look like the ones that have those nasty thorns." Then I look at my tires... COVERED in thorns. All our tires were flat in a few seconds. Luckily, we were less than 1/4 mile from home. Unluckily, it took three hours to get all the thorns out of both of our bikes.
