A group of high school friends and I started going to San Onofre for surf trips when we were 16, so I guess it started around 1984. We've been able to do the trip annually since then, save for a couple of years here and there.
It's been funny to watch the progression: At first, we were driving the parents' cars and using the families' camping gear, then driving our own cars and using our own camping gear. These days, there are at least two trailers, a motor home, several barbecues, amazing food day and night, blenders, and a fully stocked bar.
And to think we used to make fun of those old guys.
