Hi, welcome to the group. I am from Arcadia, CA, which is just East of Pasadena and about 120 mi. or so North of you. I am also an early retiree but also run a small business. I restore old telephones and radios (occasionally old Rolleiflex's and other cameras as well). Most of my sales are on ebay, and I always use film for the photos. In fact most of the time I use a Rollei 2.8E (1956-59), frequently with the Rollekin adapter which allows me to shoot 35mm film (faster and cheaper processing). I think I have less spare time after retirement than before!
I'm new here too, but welcome. I'm originally from Escondido, now living in San Antonio. Some people from Santee just moved into our hood - small world. Enjoy your photo classes, I took every one offered during my years at UCSD and loved them. I miss being in that environment.
