Landing my first front loop within 10 minutes of getting on the water at HPP. That and the chilled out session we had at Boulters Summer '06 with a BBQ and the pour-over.
Worst experience
Not being able to roll up a Dagger Juice about 1/2 a mile out to sea. Or the embarasment of not being able to roll a Wavesport X and having to swim in a canal in the middle of February.
