I met David Mayo when he arrived in La Quinta when LRH was ill. David Mayo audited and did help LRH in his recovery and the subsequent discovery and codification of Ned for OTs. He did also get NOTs and Solo NOTs implemented at the FSO and AOs. We were good friends until Broeker and Miscavige busted him, which to this day I don’t fully understand. He audited me and was my CS, with his wife Merrilll being my auditor and Qual terminal until I got to OT III, and remains a good friend. We did share some good times and adventures on a personal level in those days ’78-82.
