I was a twenty-something when I got into cb radio, thanks to my father-in-law, who never drove a truck, but was a real rag-chew on the local scene with his imax 2k, push-up pole, coax draped over the roof, going in thru a window. I thought it was strange, cb radios belonged in a truck, not inside the house on a desk.
Not long after that, I found out a friend of mine, 60 something, blind, was a ham operator with a station and 2 towers. I heard he would climb his towers in the middle of the night, so his neighbors wouldn't see him and freak out. I guess if you're blind, day or night doesn't matter. He had a nice station, got a little offended when I called it a cb radio, then, a man without sight, proceeded to open my eyes to amateur radio. Rip friend.
No, I don't see many millennials or later in this hobby, as the youngest guy in my local group, (mostly 50-80 year olds) and I find less interest in the hobby with those younger. My children could care less to talk to someone in Australia or the UK on a radio, they can do that from the game console or computer. They can interact deeper and richer than on a radio. They don't have to wait for atmospheric conditions or sun spots, I imagine that's why they don't get it, they're the "right-now, always open" generation.
