First puncture in 2 years of riding. I was riding and heard an odd rhythmic noise from the front wheel. Looked and something was on the tire. Stopped and it looked like a rock between the knobs. Flicked it out of the tire and heard the air escaping and saw the white sealant. Seconds later no more air sound and my ride continued. Delightfully uneventful. Thats all. Just happy I went tubeless.
