Matt,
That's quite a coincidence about Trinca. I took lessons there and soloed on Pete Billow's Piper J3 in about 1973. Pete and a lady (forget her name - maybe Rhonda) were the two instructors at Trinca. I think Pete might have owned the airport at that time. My dad was a partner with two airline pilots on another J3, which they kept at Trinca. Later he a Cessna 150 and kept it there for several years.

I read a few years ago that the airport had been sold and would be turned into a housing development. I hope that plan fell through.

Regards,
Jon
