Hi there, I was recently approached by one of my dad's colleagues about ideas for a retirement gift for him. He's completing his final year as a high school social studies teacher and has also been a guidance counselor and worked in admin. His colleague said they'd have at least $50 to spend, and they are also getting him a restaurant gift certificate. Physical issues restrain him from doing anything active, and we live in a rural area. I've been scratching my head about what to suggest. Any ideas? Thanks!!
