I am 56 but don't feel old or grumpy.
I live in Reno and now mostly dive the mountain lakes in the Sierra Nevada.
I was certified in 1968 (NAUI, NASDS, and YMCA). Yes, I do have a pretty good vintage collection, mostly bought new. Dove California for the first 16 years, then the job took me to Chicago for 13 years where I dove the Great Lakes and local quarries. My employer imploded on itself in 2002 so I took a new job in Reno.

Technical: NSS-CDS and NACD Full Cave (1992), DSAT and TDI Advanced Trimix (2007), KISS CCR (TDI 2007) both Sport and Classic.
