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!
