That is going way back! I remember the whippets! Donnita was a 110 (95?) lb bad ass pilot, and probably the first female to fly a hang glider. Dave's Easy Riser (best name ever for an aircraft, post the film Easy Rider) days were after my time with them.
When I met them, I was living in Carmel CA with a (in retrospect) very wealthy girlfriend, and after meeting them at the Coyotes Hills site, we hooked up after they found out I was quite close to Big Sur, and knew the area. He had his eye on that area for potential launch sites, and just needed a local to point him in the right direction, I helped with finding ways to get up to the various launch sites. The best one was San Martin Top, 2600' vert, pretty much above Jade Beach, at least within the 3-4 to 1, glide ratio we had back then. The catch was the tide, high tide and it got real tight, so tight that you were going to get wet. I've got a few pictures of me flaring for a picture perfect landing in knee deep surf, then seconds later damn near getting swept out to sea when the next wave came in. Dave and Donnita overnighted at our Carmel place several times, and I clearly remember one time he showed me this new high tech device, a hand held calculator! It was about the size of a WW2 era walkie talkie, and had just basic functions, ( no texting or internet access!) but it was the prototype of the first hand held calculator. As I recall, Dave was a tool and die maker at Hewlett Packer, his day job, and this prototype was a near top secret device. This would have been 1972.
As long as we are in the way back machine..... I found out years later, that my girlfriend's step father, who, along with her mother, we had a very formal dinner with, served by their butler no less, with once a month at "our" Carmel house (her mother and step father had a big place in Carmel Valley) was, without going into a long story, was Dwight Marrow Jr. Yes, the brother-in-law of Charles Lindbergh. HE NEVER let me know that fact, even after I remarked one time at dinner, after a HG flight off a hill at the mouth of the Carmel Valley, that the ranch caretaker made a casual remark "you know, the last person to fly a glider off this hill was Charles Lindbergh." In retrospect, it was probably because of the Marrow/Lindbergh families habitual avoidance of the media after the baby got kidnapped.
Out of the many (but true) aviation related BS stories I have in my, around the camp fire file, that right there is my best.
