My grandpa: then and now

I love my grandpa, he's always treated me like a grandson to toughen me up! My grandpa's always been very active and quite handy with technology. He used to collect random radio parts and put them together to make brand new radios. At a young 82, I can't wait for him to see (and take apart) any new technology that comes out. Pictured are my grandpa in his 50's (when I was born) and now at 82.
